Product details
Overview
MAX1182ECM from Maxim Integrated is a dual 10-bit, 65Msps analog-to-digital converter optimized for high-dynamic-performance imaging and IF undersampling applications. It operates from a single 2.7V–3.6V analog supply, delivers 59dB SNR at 20MHz input frequency, features fully differential 400MHz (-3dB) T/H inputs, and integrates a 2.048V precision bandgap reference.
For engineers reviewing the MAX1182ECM datasheet, MAX1182ECM pinout, MAX1182ECM application, or MAX1182ECM equivalent, key selection considerations include channel-to-channel gain/phase matching (±0.02dB / ±0.25°), parallel CMOS-compatible outputs with selectable two's complement/offset binary format, low-power sleep (2.8mA) and shutdown (1µA) modes, and operation across –40°C to +85°C.
Technical Context
The MAX1182ECM employs a 9-stage pipelined architecture with 1.5-bit flash ADCs per stage and digital error correction to guarantee no missing codes. Each pipeline stage uses DAC-based residue generation and amplification, achieving 5-clock-cycle data latency and supporting continuous 65Msps sampling.
Its fully differential track-and-hold circuits feature 400MHz full-power bandwidth and support both differential (±1VP-P) and single-ended analog inputs. The internal reference structure allows flexible configuration-internal 2.048V bandgap, buffered external reference via REFIN, or unbuffered external reference-with REFP/REFN/COM as programmable low-impedance outputs or high-impedance inputs depending on mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size (≈1mV for ±1.024V range) and dynamic range ceiling |
| Sampling Rate | 65Msps - enables Nyquist-limited baseband capture up to 32.5MHz or IF undersampling of higher-frequency signals |
| SNR @ 20MHz | 59dB typical - determines minimum detectable signal level in noise-limited RF/IF digitization |
| Input Bandwidth | 400MHz (-3dB) - supports faithful acquisition of fast-rising waveforms and wideband IF signals without attenuation |
| Power Dissipation | 195mW typical at 65Msps - balances performance and thermal load in space-constrained imaging or instrumentation PCBs |
| Channel Matching | ±0.02dB gain / ±0.25° phase - ensures amplitude and timing coherence between dual channels for I/Q demodulation accuracy |
| Reference Voltage | 2.048V internal bandgap - provides stable, temperature-compensated full-scale range without external components |
Pinout & Package
MAX1182ECM is housed in a 48-pin TQFP package with exposed paddle (C48E-7), rated for –40°C to +85°C operation and optimized for thermal dissipation in high-speed ADC applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+, INA- | Channel A differential analog input | Accepts ±1VP-P fully differential signal; matched impedance required for optimal SFDR |
| INB+, INB- | Channel B differential analog input | Independent second channel for simultaneous I/Q or dual-sensor digitization |
| CLK | Sampling clock input | Rising-edge triggered; requires low-jitter source (<2ps RMS) to preserve 59dB SNR at 20MHz |
| T/B | Output format select | High = two's complement; Low = offset binary - configures digital interface for DSP/FPGA logic compatibility |
| OE | Output enable | Active-low control for three-state digital outputs (D0A–D9A, D0B–D9B) to prevent bus contention |
| PD, SLEEP | Power management inputs | PD = full shutdown (1µA); SLEEP = partial bias retention (2.8mA) - enables rapid wake-up (1.5µs) |
| REFOUT, REFIN, REFP, REFN, COM | Reference system terminals | Support internal, buffered external, or unbuffered external reference configurations with programmable full-scale range |
| D0A–D9A, D0B–D9B | Parallel digital outputs | CMOS-compatible, separately powered (OVDD = 1.7V–3.6V), 5-cycle latency - enables direct FPGA/ASIC interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit pipelines | Enables simultaneous sampling of I/Q signals or dual sensor channels without time skew or resource contention |
| 400MHz full-power analog input bandwidth | Preserves signal integrity for IF undersampling up to ~30MHz without external anti-alias filtering |
| 0.02dB gain / 0.25° phase channel matching | Minimizes image rejection degradation in quadrature receivers - critical for <–70dBc image suppression |
| Configurable reference architecture | Internal 2.048V reference eliminates external components; buffered/unbuffered external modes support custom full-scale ranges |
| Separate OVDD supply (1.7V–3.6V) | Allows interfacing with 1.8V or 2.5V logic domains without level shifters, reducing BOM and layout complexity |
| 5-clock-cycle deterministic latency | Enables precise timing alignment in real-time processing loops and simplifies FIFO depth calculation in FPGA buffers |
Applications
| High-Resolution Imaging | I/Q Channel Digitization |
|---|---|
Use Scenario: Digitizing output from CCD/CMOS image sensors in medical ultrasound or industrial X-ray systems requiring >60dB dynamic range. IC Role / Device Role / Timing Role: Dual-channel ADC captures synchronized analog pixel streams with matched gain/phase to preserve spatial fidelity and contrast linearity. Use Value: 59dB SNR and ±0.02dB channel matching directly translate to improved signal-to-noise ratio in reconstructed images and reduced fixed-pattern noise. |
Use Scenario: Converting quadrature-mixed RF signals in software-defined radios or LTE baseband receivers. IC Role / Device Role / Timing Role: Simultaneous sampling of in-phase (I) and quadrature (Q) analog paths with sub-degree phase coherence. Use Value: 0.25° phase matching ensures <–70dBc image rejection; 400MHz input bandwidth supports direct IF sampling at 70MHz or 140MHz. |
| Multichannel IF Undersampling | Instrumentation Data Acquisition |
Use Scenario: Capturing multiple intermediate-frequency signals (e.g., 40–60MHz) in spectrum analyzers or radar front ends using aliasing techniques. IC Role / Device Role / Timing Role: High-input-bandwidth ADC operating at 65Msps to undersample bands above Nyquist while maintaining SFDR >77dBc. Use Value: 77dB SFDR at 20MHz input and 400MHz full-power bandwidth eliminate need for steep analog filters, reducing system cost and insertion loss. |
Use Scenario: High-fidelity waveform capture in portable oscilloscopes or automated test equipment requiring low power and wide dynamic range. IC Role / Device Role / Timing Role: Low-power dual ADC with sleep mode (2.8mA) and shutdown (1µA) for battery-operated instruments with burst acquisition. Use Value: 195mW active power and 1µA shutdown current extend field-deployable instrument runtime without compromising 10-bit resolution or SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 10-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1183ECM | 40Msps sampling rate; identical pinout, reference architecture, and 10-bit resolution | Lower power (120mW) and relaxed clock jitter requirements - suited for cost-sensitive IF sampling where 65Msps is unnecessary | Select when system clock stability or power budget precludes 65Msps operation but full MAX1182 feature set (dual channel, matching, reference flexibility) is retained |
| ADS5272IPFP | 12-bit resolution, 65Msps, separate analog/digital supplies, no integrated reference - requires external 2.048V reference and level-shifting | Better SNR (66dB) and SFDR (85dBc) at expense of higher power (450mW) and board area; no sleep/shutdown modes | Choose for applications demanding higher resolution and dynamic range where power and integration are secondary to performance |
Compared with MAX1183ECM, MAX1182ECM delivers 25Msps higher throughput and 75mW higher power for wideband IF capture; compared with ADS5272IPFP, MAX1182ECM trades 2-bit resolution for integrated reference, lower power, and power-management modes - favoring compact, self-contained designs over ultimate SNR.

FAQ
What is the maximum analog input frequency supported by the MAX1182ECM?
The MAX1182ECM supports a full-power analog input bandwidth of 400MHz (-3dB), enabling accurate digitization of signals up to this frequency in differential mode. Its small-signal bandwidth extends to 500MHz, making it suitable for IF undersampling applications well beyond its 65Msps Nyquist limit. This specification is validated under standard conditions (VDD = 3V, fCLK = 65MHz, differential input).
Does the MAX1182ECM require an external reference voltage?
No, the MAX1182ECM includes an internal 2.048V precision bandgap reference that sets the full-scale range. It can operate in internal reference mode by connecting REFOUT to REFIN through a 10kΩ resistor. External references are optional and supported in buffered or unbuffered configurations - the MAX1182ECM does not require external components for basic operation.
How does the MAX1182ECM manage power in low-duty-cycle systems?
The MAX1182ECM offers two low-power states: a 2.8mA sleep mode (reference bias active, ADCs disabled) and a 1µA power-down mode (full shutdown). Wake-up times are 0.42µs from sleep and 1.5µs from shutdown. These modes allow rapid reactivation during burst acquisition, making the MAX1182ECM ideal for battery-powered instrumentation and intermittent-sampling systems.
What digital output formats does the MAX1182ECM support, and how are they selected?
The MAX1182ECM supports two digital output formats: two's complement and straight offset binary. Selection is controlled by the T/B pin: logic high selects two's complement; logic low selects offset binary. Both formats are delivered on parallel CMOS-compatible outputs (D0A–D9A and D0B–D9B) with 5-clock-cycle latency and configurable OVDD (1.7V–3.6V) for logic-level flexibility.
Is the MAX1182ECM pin-compatible with other devices in the MAX118x family?
Yes, the MAX1182ECM is pin-compatible with the MAX1180 (105Msps), MAX1181 (80Msps), MAX1183 (40Msps), and MAX1184 (20Msps), all in the same 48-pin TQFP-EP package. This allows drop-in speed upgrades or downgrades without PCB redesign. The MAX1185 (20Msps multiplexed output) shares the footprint but differs in pin function and must be evaluated separately.
