Product details
Overview
The MAX1184ECM+D from Maxim Integrated is a dual 10-bit, 20Msps analog-to-digital converter optimized for low-power, high-dynamic-performance signal digitization in imaging and instrumentation systems. It features fully differential track-and-hold inputs, 400MHz (-3dB) input bandwidth, 59.5dB SNR at 7.5MHz input, and operates from a single 2.7V–3.6V analog supply while consuming only 105mW.
For engineers reviewing the MAX1184ECM+D datasheet, MAX1184ECM+D pinout, MAX1184ECM+D application, or MAX1184ECM+D equivalent, this page delivers verified specifications, channel-matched performance data, parallel CMOS-compatible output timing, and thermal-aware TQFP-EP package implementation guidance.
Technical Context
The MAX1184ECM+D employs a 9-stage pipelined ADC architecture with 1.5-bit flash stages and digital error correction to guarantee no missing codes and ±1.5 LSB INL. Each channel uses independent fully differential track-and-hold amplifiers with 400MHz full-power bandwidth and 500MHz small-signal bandwidth.
It supports three reference configurations: internal 2.048V bandgap (±3% accuracy, 60ppm/°C TC), buffered external reference via REFIN, or unbuffered external reference with high-impedance REFP/REFN/COM. Output format (two's complement or offset binary) is selected by the T/B pin, and digital outputs are CMOS-compatible with separate 1.7V–3.6V OVDD supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size of ~1 mV for ±1 VP-P differential input range |
| Sampling Rate | 20 Msps - enables Nyquist-limited baseband capture up to 10 MHz or IF undersampling in communications |
| SNR @ 7.5 MHz | 59.5 dB (typ) - determines effective number of bits (ENOB ≈ 9.6) for high-fidelity waveform digitization |
| Input Bandwidth | 400 MHz (-3dB) - supports wideband analog input signals without external pre-filtering |
| Power Consumption | 105 mW (normal), 2.8 mA (sleep), 1 µA (shutdown) - enables dynamic power scaling in battery-sensitive or thermally constrained systems |
| Channel Matching | ±0.02 dB gain, ±0.25° phase - ensures coherent I/Q sampling integrity for quadrature demodulation |
| Reference Voltage | 2.048 V internal bandgap (±3%, 60 ppm/°C) - provides stable full-scale range without external components |
Pinout & Package
MAX1184ECM+D is housed in a 48-pin TQFP package with exposed paddle (7mm × 7mm) for enhanced thermal dissipation. The exposed paddle must be connected to analog ground (GND) for optimal thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+, INA− / INB+, INB− | Differential analog inputs (Channel A / B) | Accept ±1 VP-P differential or single-ended signals; require matched impedance and VCM = VDD/2 |
| COM | Common-mode voltage node | Serves as reference midpoint for differential inputs and internal reference buffer; bypass to GND with ≥0.1 µF |
| CLK | Sampling clock input | CMOS-compatible rising-edge-triggered clock; jitter ≤2 ps RMS critical for SNR preservation |
| T/B | Output format select | High = two's complement; Low = straight offset binary - configures MSB polarity for DSP interface alignment |
| OE, PD, SLEEP | Digital control inputs | OE enables/disables parallel outputs; PD enters 1 µA shutdown; SLEEP reduces current to 2.8 mA while retaining reference bias |
| D0A–D9A / D0B–D9B | Parallel CMOS digital outputs | 10-bit per channel, three-state, with separate OVDD (1.7–3.6 V) for flexible logic-level interfacing |
| REFOUT, REFIN, REFP, REFN | Reference interface terminals | Support internal, buffered external, or unbuffered external reference modes; REFP/REFN define ±(VREFP−VREFN) full-scale range |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit pipelines | Enables simultaneous sampling of I/Q or dual-channel sensor data with guaranteed code monotonicity and no missing codes |

| 0.02 dB / 0.25° channel-to-channel matching | Preserves vector accuracy in quadrature receivers and phased-array front-ends |
| Separate OVDD supply (1.7–3.6 V) | Allows seamless interfacing with 1.8 V, 2.5 V, or 3.3 V FPGA or ASIC logic domains |
| Exposed paddle TQFP-EP package | Reduces junction-to-board thermal resistance by >30% versus standard TQFP, critical for sustained 105 mW operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 10-bit, 20Msps ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1185ECM+ | Same pinout, but multiplexed 10-bit output (time-interleaved on single bus); identical analog specs and power | Reduces PCB trace count and FPGA I/O usage; requires deserialization logic in host processor | Select MAX1185ECM+ when board space or FPGA pin count is constrained and host can handle time-multiplexed data |
| AD9215BRUZ-20 | 10-bit, 20 Msps, single-channel; no channel matching spec; higher 115 mW power; different 32-lead TSSOP package | Requires two devices for dual-channel use; lacks guaranteed inter-channel gain/phase match | Choose AD9215BRUZ-20 only for non-coherent dual-channel systems where cost-per-channel outweighs matching requirements |
Compared with MAX1185ECM+, the MAX1184ECM+ offers native parallel dual-channel outputs for simpler timing-critical interfaces; compared with AD9215BRUZ-20, it delivers guaranteed channel matching and lower power in a thermally optimized 48-pin TQFP-EP package.

FAQ
What is the absolute maximum clock frequency supported by the MAX1184ECM+D?
The MAX1184ECM+D supports a maximum clock frequency of 20 MHz, as specified in its Electrical Characteristics table. Operation beyond this frequency violates timing margins and may cause metastability, increased DNL, or data corruption. The device achieves optimal SNR and SFDR performance precisely at 20 Msps with proper clock jitter control (<2 ps RMS).
Does the MAX1184ECM+D require external decoupling capacitors, and if so, where?
Yes, the MAX1184ECM+D requires external decoupling: each VDD pin (pins 2, 6, 11, 14, 15) must be bypassed to GND with a 0.1 µF capacitor; REFP, REFN, and COM require ≥0.1 µF capacitors to GND; REFIN needs >1 nF; and OVDD pins (32, 33) require 0.1 µF to OGND. These are mandatory for stable reference operation and analog performance.
Can the MAX1184ECM+D operate with single-ended analog inputs?
Yes, the MAX1184ECM+D supports single-ended operation: connect the signal source to INA+ (or INB+) and tie INA− (or INB−) to COM. However, differential mode is strongly recommended for best SNR, SFDR, and common-mode noise rejection. Single-ended use degrades dynamic performance by ~3–5 dB due to reduced CMRR and increased even-order distortion.
What is the function of the exposed paddle (EP) on the MAX1184ECM+D package?
The exposed paddle (EP) on the MAX1184ECM+D serves as a thermal and electrical connection point. It must be soldered to a solid analog ground plane to reduce junction temperature by up to 25°C and minimize ground bounce. Leaving EP floating or connecting it to digital ground violates the Absolute Maximum Ratings and risks parametric shift or latch-up.
How does the T/B pin affect digital output coding in the MAX1184ECM+D?
The T/B pin selects output format: logic high configures MAX1184ECM+D for two's complement coding (e.g., 0x000 = −1.024 V, 0x200 = 0 V, 0x3FF = +1.023 V); logic low selects straight offset binary (0x000 = −1.024 V, 0x200 = 0 V, 0x3FF = +1.023 V). This single-pin control eliminates external configuration logic and simplifies FPGA interface design.
