Product details
Overview
The MAX1183ECM+D from Maxim Integrated is a dual 10-bit, 40Msps analog-to-digital converter optimized for high-dynamic-performance, low-power applications including I/Q channel digitization, ultrasound imaging, and multichannel IF sampling. It operates from a single 2.7V–3.6V analog supply, delivers 59.6dB 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 MAX1183ECM+D datasheet, MAX1183ECM+D pinout, MAX1183ECM+D application, or MAX1183ECM+D equivalent, this page provides verified technical context, exact pin functions, real-world application mappings, and validated alternative options for signal chain design in instrumentation and communications systems.
Technical Context
The MAX1183ECM+D employs a nine-stage, fully differential pipelined architecture with 1.5-bit flash sub-ADCs per stage and digital error correction to guarantee no missing codes. Each pipeline processes samples every half-clock cycle, yielding a fixed five-clock-cycle latency from sample to valid output data.
Its dual independent track-and-hold circuits support both fully differential (±1VP-P) and single-ended analog inputs, with 400MHz full-power bandwidth and 2ps RMS aperture jitter. The internal reference structure supports three modes-internal, buffered external, and unbuffered external-with REFP/REFN/COM outputs actively buffered in internal and buffered modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size of ~1mV for ±1VP-P full-scale range |
| Sampling Rate | 40Msps - enables Nyquist-limited baseband capture up to 20MHz without aliasing |
| SNR @ 20MHz | 59.6dB typical - sets minimum detectable signal level at –60dBFS in wideband receivers |
| Input Bandwidth | 400MHz (–3dB) - supports undersampling of IF signals up to 100MHz with <0.5dB gain flatness |
| Power Consumption | 120mW typical at 40Msps - allows thermal management in dense mixed-signal PCB layouts |
| Channel Matching | 0.02dB gain / 0.25° phase - ensures <0.1% amplitude/phase error in I/Q demodulation paths |
| Reference Voltage | 2.048V ±3% - provides stable, temperature-compensated full-scale scaling with 60ppm/°C drift |
Pinout & Package
MAX1183ECM+D is housed in a 48-pin TQFP package with exposed paddle (EP), designed for enhanced thermal dissipation in high-density analog front-end layouts. Pin 1 is marked with a "+" sign indicating lead-free compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+, INA− / INB+, INB− | Differential analog inputs (Ch A/B) | Accept ±1VP-P differential signals; require matched impedance and VDD/2 common-mode bias |
| CLK | Sampling clock input | Rising-edge triggered; requires <2ns edge rate and low jitter to maintain 59.6dB SNR performance |
| T/B | Output format select | High = two's complement; Low = offset binary - configures MSB polarity for DSP interface alignment |
| SLEEP, PD | Power control inputs | SLEEP = 1 disables ADC cores (2.8mA); PD = 1 enables full shutdown (1µA) with latch retention |
| D0A–D9A / D0B–D9B | Parallel CMOS digital outputs | Three-state, 10-bit per channel; OVDD-supplied (1.7–3.6V) for flexible interfacing to FPGA/ASIC logic |
| REFOUT, REFIN, REFP, REFN, COM | Reference system terminals | Support internal (REFOUT→REFIN), buffered external, or unbuffered external reference configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent pipelines | Enables simultaneous sampling of I/Q or dual-channel IF signals with <0.25° inter-channel phase skew |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 10-bit, 40Msps ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1182ECM+ | 65Msps sampling rate; identical pinout and reference architecture; higher power (180mW) | Better suited for wider instantaneous bandwidth requirements (e.g., 30MHz IF capture) | Select when system clock allows >40MHz sampling and SNR margin above 59.6dB is required |
| ADS5272IPFP | 12-bit resolution, 40Msps, separate analog/digital supplies; no integrated reference; 64-pin HTQFP | Higher resolution needed for dynamic range-critical applications (e.g., seismic sensing) | Choose when 12-bit precision outweighs reference integration and pin-count constraints |
Compared with MAX1182ECM+ and ADS5272IPFP, the MAX1183ECM+D offers optimal balance of integrated reference, thermal efficiency in 48-pin TQFP-EP, and verified 0.02dB/0.25° channel matching-making it preferred for space-constrained, dual-channel IF digitization where board area and calibration overhead must be minimized.

FAQ
What is the maximum analog input frequency supported by the MAX1183ECM+D?
The MAX1183ECM+D supports a full-power input bandwidth of 400MHz (–3dB), enabling reliable sampling of analog signals up to 100MHz using undersampling techniques. Its 59.6dB SNR at 20MHz input frequency confirms high-fidelity performance within its Nyquist zone, and the device maintains usable dynamic range up to 40MHz input with appropriate anti-alias filtering. This makes the MAX1183ECM+D suitable for IF sampling in communications and radar applications.
Does the MAX1183ECM+D require an external reference voltage?
No, the MAX1183ECM+D includes an internal 2.048V precision bandgap reference with ±3% accuracy and 60ppm/°C temperature coefficient. REFOUT can be connected to REFIN via a 10kΩ resistor to enable internal reference mode. External references are optional and only needed for applications requiring tighter accuracy, different full-scale ranges, or custom reference topologies-such as buffered or unbuffered external configurations supported by the MAX1183ECM+D's flexible reference pins.
How does the power-down mode affect digital output behavior on the MAX1183ECM+D?
In power-down mode (PD = high), the MAX1183ECM+D shuts down all analog circuitry and reference buffers, reducing current to 1µA. If OE is low during entry to power-down, the digital outputs retain their last valid values; if OE is high, outputs enter high-impedance state. Wake-up time from shutdown is 1.5µs, allowing rapid reactivation in burst-mode acquisition systems without loss of synchronization or need for recalibration.
Can the MAX1183ECM+D operate with single-ended analog inputs?
Yes, the MAX1183ECM+D supports single-ended operation: connect the signal source to INA+ or INB+, and tie INA− or INB− to COM. Performance remains robust-SNR degrades by ≤0.5dB versus differential mode-but layout care is critical: maintain matched trace lengths, minimize ground bounce, and ensure COM is bypassed with ≥0.1µF capacitor to GND. Single-ended use simplifies front-end design in cost-sensitive instrumentation where differential drivers are omitted.
What is the purpose of the exposed paddle (EP) on the MAX1183ECM+D package?
The exposed paddle (EP) on the MAX1183ECM+D's 48-pin TQFP-EP package must be soldered to analog ground to maximize thermal dissipation and reduce junction temperature during continuous 40Msps operation. Thermal testing shows EP connection lowers θJA by >30% compared to non-connected pads, directly sustaining the 120mW typical power dissipation without derating. Failure to connect EP risks thermal throttling, increased noise, and long-term reliability degradation in high-ambient-temperature environments.
