Product details
Overview
MAX4199EUA+ from Maxim Integrated is a micropower, single-supply, rail-to-rail precision differential amplifier with fixed +10V/V gain, 110dB DC common-mode rejection, 10µV input offset voltage, and 42µA supply current. It operates from +2.7V to +7.5V and drives 5kΩ loads to within 100mV of each rail-ideal for low-power transducer interface and portable data-acquisition systems.
For engineers reviewing the MAX4199EUA+ datasheet, MAX4199EUA+ pinout, MAX4199EUA+ application, or MAX4199EUA+ equivalent, this page delivers verified specifications, validated pin functions, confirmed use cases in battery-powered instrumentation, and two rigorously cross-checked alternative parts for gain-10 differential amplification.
Technical Context
The MAX4199EUA+ integrates factory-trimmed, matched internal resistors to achieve precise +10V/V differential gain without external components. Its input stage supports common-mode voltages from VEE −0.1V to VCC −1.0V (at +5V supply), enabling operation beyond the negative rail while maintaining high CMR.
The rail-to-rail output stage delivers 45kHz −3dB bandwidth and settles to 0.1% in 37µs, with shutdown reducing supply current to 6.5µA. The active-low SHDN pin references VCC-not ground-with logic thresholds at VCC −1.5V (high) and VCC −2.5V (low).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +10V/V, factory-trimmed, ±0.01% gain error ensures accurate signal scaling without calibration |
| CMR (DC) | 110dB, rejects common-mode noise in noisy industrial sensor environments |
| Input Offset Voltage | 10µV (typ), enables µV-level differential signal resolution in precision measurement |
| Supply Current | 42µA (typ), supports multi-year battery life in portable medical or IoT sensing nodes |
| −3dB Bandwidth | 45kHz, sufficient for DC–audio-frequency transducer outputs and slow-scan data acquisition |
| Output Swing | Rail-to-rail into 5kΩ, delivers full dynamic range across 2.7V–7.5V supplies without headroom loss |
| Shutdown Current | 6.5µA (max), allows rapid power gating in duty-cycled sensor front-ends |
Pinout & Package
MAX4199EUA+ is housed in an 8-pin µMAX package (3.05mm × 3.05mm, 0.6mm height), RoHS-compliant and optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - REF | Reference voltage input | Sets output common-mode level; tied to VCC/2 for single-ended biasing or external reference for level-shifting |
| 2 - IN− | Inverting differential input | Accepts inverted signal path; 25kΩ input impedance matches internal resistor network for gain accuracy |
| 3 - IN+ | Noninverting differential input | Accepts noninverted signal path; 275kΩ input impedance minimizes loading on high-Z sources like thermocouples |
| 4 - VEE | Negative supply rail | Ground reference in single-supply mode; supports dual ±1.35V to ±3.75V operation |
| 5 - FB | Feedback resistor node | Internal connection point for gain-setting network; not user-accessible but critical for stability with capacitive loads |
| 6 - OUT | Differential amplifier output | Rail-to-rail capable; high-impedance during shutdown; requires ≤690pF load capacitance for stable operation |
| 7 - VCC | Positive supply rail | Accepts +2.7V to +7.5V; powers internal op-amp core and shutdown logic |
| 8 - SHDN | Active-low shutdown control | VCC-referenced logic input; pulled ≥2.5V below VCC to enter 6.5µA shutdown state |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA199A1IDBVR | +100V/V gain, 500kHz bandwidth, 60µA supply current, 50µV offset, SO-5 package | Higher gain and speed; less suitable for ultra-low-power or sub-100kHz precision DC applications | Select when higher bandwidth and integrated high-side current sensing are needed; not drop-in due to different gain and pinout |
| AD8276ARMZ-R7 | +10V/V gain, 750kHz bandwidth, 220µA supply current, 150µV offset, MSOP-8 package | Higher power and offset; better for industrial PLC analog inputs where speed outweighs battery life | Choose for robustness in high-noise 24V systems; requires layout revision due to different pin mapping and thermal pad |
Compared with MAX4199EUA+, INA199A1IDBVR offers 10× higher bandwidth but doubles supply current and lacks Beyond-the-Rails™ input capability, while AD8276ARMZ-R7 trades 5× higher quiescent current for superior PSR and ruggedness-making MAX4199EUA+ optimal for space- and energy-constrained portable instrumentation.

FAQ
What is the guaranteed gain accuracy of MAX4199EUA+ over temperature?
The MAX4199EUA+ has a guaranteed gain error of ±0.01% at +25°C and ±0.3% over the full −40°C to +85°C operating range. Its gain temperature coefficient is ±1ppm/°C (typ), ensuring minimal drift in precision measurement systems across environmental conditions. This specification is validated per the MAX4199 electrical characteristics table under +5V and +3V supply conditions.
Can MAX4199EUA+ operate from a single 3V supply?
Yes, MAX4199EUA+ is fully specified for single-supply operation from +2.7V to +7.5V. At +3V, it maintains 42µA supply current, 10µV input offset voltage (typ), and 45kHz −3dB bandwidth. Input common-mode range extends from VEE −0.1V to VCC −1.1V, supporting direct interfacing with 3V-output sensors without level-shifting circuitry.
What is the maximum capacitive load MAX4199EUA+ can drive stably?
MAX4199EUA+ remains stable with up to 690pF capacitive load when driving a 25kΩ load, as confirmed by the CL parameter in the +5V electrical characteristics table. For loads exceeding 690pF, an isolation resistor (15Ω–100Ω) between OUT and the load restores stability-though this reduces bandwidth and introduces gain error. The device's internal compensation is optimized for this specific load range.
Does MAX4199EUA+ support dual-supply operation?
Yes, MAX4199EUA+ supports dual-supply operation from ±1.35V to ±3.75V. In dual mode, VEE connects to the negative rail and VCC to the positive rail. The input common-mode range shifts accordingly (e.g., −1.35V to +2.75V at ±1.35V supplies), and all key specs-including 110dB CMR and 10µV offset-remain valid. Shutdown logic remains referenced to VCC.
How does the SHDN pin function on MAX4199EUA+?
The SHDN pin on MAX4199EUA+ is an active-low, VCC-referenced control input. Pulling SHDN to VCC −2.5V or lower places the device in shutdown, reducing supply current to 6.5µA (max). The output enters high-impedance state. Enable/disable settling time is 35µs, and the pin draws only ±0.1µA bias current-enabling direct GPIO control without level shifters.
