Product details
Overview
MAX4387EUA+ from Maxim Integrated is a dual, high-speed, voltage-feedback operational amplifier optimized as an ADC buffer for communications and instrumentation systems. It operates from a single +2.85V to +6.5V supply, delivers 150MHz −3dB bandwidth (at gain = +5V/V), 350V/µs slew rate, 8ns settling time (to 0.1%), and −88dBc SFDR at 5MHz - enabling precise, low-distortion signal conditioning ahead of high-speed analog-to-digital converters.
For engineers reviewing the MAX4387EUA+ datasheet, MAX4387EUA+ pinout, MAX4387EUA+ application, or MAX4387EUA+ equivalent, key selection criteria include its dual-channel architecture with noninverting gain-of-5 stability, absence of disable functionality, 8-pin µMAX package constraints, and verified performance driving 300Ω loads in ADC front-end multiplexing and CCD imaging paths.
Technical Context
The MAX4387EUA+ is internally compensated for stable operation at minimum closed-loop gain of +5V/V, distinguishing it from unity-gain-stable variants like MAX4287. Its voltage-feedback topology supports wideband AC-coupled signal chains with input common-mode range extending to VEE (ground in single-supply use) and output swing from (VEE + 0.4V) to (VCC − 0.4V).
It features matched input offset voltage (±0.2mV typ), low input bias current (0.2µA max), 10nV/√Hz input voltage noise density at 1MHz (+3V supply), and crosstalk of −85dBc at 10MHz - confirming suitability for dual-channel, high-fidelity acquisition where inter-channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3dB Bandwidth | 150MHz at AV = +5V/V - ensures full-signal fidelity through Nyquist zone of 75Msps+ ADCs |
| Slew Rate | 350V/µs - supports clean reproduction of fast-rising digital or RF-modulated waveforms |
| Settling Time | 8ns to 0.1% - meets timing budget for sub-10ns aperture clocks in high-speed sampling systems |
| SFDR | −88dBc at fC = 5MHz - preserves ENOB > 12.5 bits for precision digitization of narrowband signals |
| Output Drive | ±106mA sink/source - directly drives low-Z ADC inputs (e.g., SAR, pipeline) without external buffers |
| Supply Range | +2.85V to +6.5V single supply - compatible with 3.3V and 5V system rails without level-shifting |
| Input CMVR | Extends to VEE - enables ground-referenced sensor interfacing in single-supply configurations |
Pinout & Package
MAX4387EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), thermally enhanced with exposed paddle, rated for −40°C to +85°C operation. Pin 1 is marked with dot; pin count and layout conform to Maxim's standard 8L_UMAX footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INA−) | Inverting input, Amplifier A | Accepts differential or single-ended feedback; requires matched trace length for optimal CMRR |
| 2 (INA+) | Noninverting input, Amplifier A | High-impedance node; sensitive to PCB leakage and parasitic capacitance above 1pF |
| 3 (OUTA) | Output, Amplifier A | Capable of ±106mA drive; requires series isolation resistor (20–30Ω) when driving >10pF loads |
| 4 (VEE) | Negative supply / Ground | Must connect to low-impedance ground plane; shared return path impacts PSRR above 10MHz |
| 5 (VCC) | Positive supply | Bypass with 0.1nF ceramic + 0.1µF tantalum placed ≤2mm from pin to suppress 100MHz+ supply noise |
| 6 (INB+) | Noninverting input, Amplifier B | Independent channel; identical DC/AC specs to INA+, supports synchronous dual-sensor buffering |
| 7 (INB−) | Inverting input, Amplifier B | Matches INA− in offset, bias, and noise; enables interleaved or parallel ADC channel pairing |
| 8 (OUTB) | Output, Amplifier B | Same drive strength and settling as OUTA; crosstalk <−85dBc ensures minimal inter-channel coupling |
Key Features
| Feature | Design Value |
|---|---|
| Gain-of-5 stability | Eliminates need for external compensation components in standard ADC driver configurations |
| Low distortion at 5MHz | −88dBc SFDR enables >12-bit ENOB preservation in baseband communication receivers |
| Input-referred voltage noise | 10nV/√Hz at 1MHz allows clean amplification of µV-level sensor outputs without SNR degradation |
| Matched channel performance | ΔVOS ≤ 0.2mV and crosstalk ≤ −85dBc support accurate differential or time-interleaved sampling |
| Single-supply rail-to-rail input | Common-mode range to VEE permits direct connection to ground-referenced transducers and DACs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4287EUA+ | Unity-gain stable; 250MHz bandwidth; no disable; same 8-pin µMAX package | Preferred for variable-gain or unity-gain ADC driver stages requiring wider bandwidth | Select when gain flexibility or higher bandwidth outweighs need for fixed +5V/V stability |
| AD8022ARMZ | Unity-gain stable; 130MHz bandwidth; 2.7V–12V supply; SO-8 package; no disable | Lower power (12mA/ch), wider supply range, but lower SFDR (−79dBc @ 5MHz) | Choose for cost-sensitive industrial DAQ where 12-bit ENOB suffices and board space allows SO-8 |
Compared with MAX4287EUA+, MAX4387EUA+ trades 100MHz bandwidth for guaranteed +5V/V stability and superior SFDR; versus AD8022ARMZ, it delivers 9dB better distortion performance at 5MHz but requires tighter layout control due to higher speed.

FAQ
Does MAX4387EUA+ support single-supply operation?
Yes, MAX4387EUA+ operates from a single +2.85V to +6.5V supply. Its input common-mode voltage range extends to VEE (ground), and output swings from (VEE + 0.4V) to (VCC − 0.4V), making it fully compatible with 3.3V and 5V single-rail systems without level-shifting circuitry. This is confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics tables of the MAX4387EUA+ datasheet.
What is the gain configuration requirement for stable operation of MAX4387EUA+?
MAX4387EUA+ is internally compensated for stable operation only at closed-loop gains ≥ +5V/V. It is not unity-gain stable. Attempting to use it at gains below +5V/V may cause peaking or oscillation. The MAX4387EUA+ datasheet explicitly states this in the Detailed Description section and Selector Guide table.
Is MAX4387EUA+ pin-compatible with MAX4287EUA+?
Yes, MAX4387EUA+ and MAX4287EUA+ share identical 8-pin µMAX pinouts and package dimensions. Both have the same pin assignments for INA−, INA+, OUTA, VEE, VCC, INB+, INB−, and OUTB. However, their internal compensation and bandwidth differ - MAX4287EUA+ is unity-gain stable (250MHz), while MAX4387EUA+ is +5V/V stable (150MHz).
Does MAX4387EUA+ include a disable function?
No, MAX4387EUA+ does not feature a disable input. Unlike MAX4388EUA+ or MAX4288EUA+, which include DISABLEA/DISABLEB pins, the MAX4387EUA+ lacks any enable/disable control. Its quiescent supply current remains at 24mA (typ) per amplifier under all operating conditions, as specified in the DC Electrical Characteristics table.
What is the maximum capacitive load MAX4387EUA+ can drive without instability?
MAX4387EUA+ is not optimized for highly reactive loads. Driving >10pF directly risks ringing or oscillation. The datasheet recommends using a 20Ω–30Ω isolation resistor in series with the output when loading >10pF. Performance graphs (e.g., Figure 1 and MA4285-21/22) confirm stable small-signal pulse response only with added series resistance for CLOAD ≥ 22pF.
