Product details
Overview
MAX4199EUA from Maxim Integrated is a micropower, single-supply, rail-to-rail precision differential amplifier with fixed +10V/V gain, 10µV input offset voltage, 110dB DC common-mode rejection, 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 current-sense applications.
For engineers reviewing the MAX4199EUA datasheet, MAX4199EUA pinout, MAX4199EUA application, or MAX4199EUA equivalent, key selection criteria include guaranteed +10V/V gain accuracy (±0.01%), Beyond-the-Rails™-compatible input range (VEE −0.1V to VCC −1.0V), shutdown current of 6.5µA, and 8-pin µMAX package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4199EUA integrates factory-trimmed precision resistors to deliver stable +10V/V differential gain without external components. Its internal op-amp stage supports common-mode inputs from VEE −0.1V to VCC −1.0V, enabling operation beyond the negative rail while maintaining high CMR.
It features an active-low SHDN pin referenced to VCC (VIH = VCC −1.5V, VIL = VCC −2.5V), enabling fast 35µs enable/disable settling and high-impedance output in shutdown. The rail-to-rail output stage delivers full swing into 5kΩ loads with <0.01% gain error over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Fixed Gain | +10V/V, factory trimmed to ±0.01% error at +25°C - eliminates external resistor matching and drift concerns |
| Input Offset Voltage | 10µV typical (±500µV max) - enables accurate amplification of sub-mV differential signals |
| DC Common-Mode Rejection | 110dB - rejects low-frequency interference in noisy industrial sensor environments |
| Supply Current | 42µA typical - supports multi-year battery life in portable instrumentation |
| -3dB Bandwidth | 45kHz at +10V/V gain - sufficient for DC–40kHz signal conditioning in data-acquisition systems |
| Shutdown Current | 6.5µA - reduces system power during idle cycles without sacrificing wake-up speed |
| Input Voltage Range | VEE −0.1V to VCC −1.0V - accommodates inputs below ground in single-supply systems |
| Output Swing | Within 100mV of rails into 5kΩ - maximizes dynamic range for ADC interfacing with 12-bit+ resolution |
Pinout & Package
The MAX4199EUA is housed in an 8-pin µMAX package (3.05mm × 3.05mm × 0.8mm), pin-compatible with industry-standard SO-8 but with 55% smaller footprint and improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF (Pin 1) | Reference voltage input | Sets output common-mode level; tied to VCC/2 for centered bipolar output swing |
| IN+ (Pin 3) | Noninverting differential input | Accepts signals up to VEE −0.1V; 275kΩ input impedance minimizes loading on high-Z sources |
| IN− (Pin 2) | Inverting differential input | 25kΩ input impedance matched to IN+ for optimal CMR; used with FB for standard diff-amp configuration |
| FB (Pin 5) | Feedback resistor terminal | Internal 25kΩ resistor connects to IN−; enables standard difference amplifier topology without external components |
| OUT (Pin 6) | Differential amplifier output | Rail-to-rail capable; high-impedance in shutdown mode - safe for multiplexed analog backplanes |
| VCC (Pin 7) | Positive supply | +2.7V to +7.5V operation; powers internal bias networks and output stage |
| VEE (Pin 4) | Negative supply / ground reference | Supports single-supply (0V) or dual-supply (±1.35V to ±3.75V) operation |
| SHDN (Pin 8) | Active-low shutdown control | Logic threshold referenced to VCC (not GND); 35µs wake-up time enables rapid power cycling |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4198EUA | Fixed +1V/V gain, 30µV VOS, 90dB CMRDC, 175kHz bandwidth | Better suited for unity-gain buffer or high-bandwidth differential signaling where gain accuracy is less critical than speed | Select when system requires minimal signal inversion or higher bandwidth with relaxed gain tolerance |

FAQ
What is the guaranteed gain accuracy of the MAX4199EUA over temperature?
The MAX4199EUA is factory trimmed to ±0.01% gain error at +25°C, with gain temperature coefficient of ±1ppm/°C. Over the full −40°C to +85°C operating range, total gain error remains within ±0.3%, verified by design and production-tested at +25°C per datasheet Note 1. This ensures stable +10V/V scaling for precision measurement systems without recalibration.
Can the MAX4199EUA operate with inputs below the negative supply rail?
Yes - the MAX4199EUA supports an input common-mode voltage range extending to VEE −0.1V (e.g., −100mV when VEE = 0V). This "Beyond-the-Rails" capability allows direct interfacing with bipolar transducer outputs or grounded shunt resistors in single-supply configurations, without external level-shifting circuitry.
What is the maximum capacitive load the MAX4199EUA can drive stably?
The MAX4199EUA remains stable with up to 590pF capacitive load (per Typical Operating Characteristics Figure MAX4198toc19). For loads exceeding this, a series isolation resistor (e.g., 75Ω) between OUT and CL restores stability - though bandwidth and DC accuracy degrade proportionally. No external compensation capacitor is required for ≤590pF.
How does the shutdown function work on the MAX4199EUA?
The MAX4199EUA features an active-low SHDN pin referenced to VCC: logic high (VIH ≥ VCC −1.5V) enables operation; logic low (VIL ≤ VCC −2.5V) places the device in shutdown, reducing supply current to 6.5µA. Output goes high-impedance, and wake-up settling time is 35µs - enabling rapid power cycling in duty-cycled sensor nodes.
Is the MAX4199EUA pin-compatible with other packages in the MAX4198/MAX4199 family?
Yes - the MAX4199EUA uses the 8-pin µMAX package, which shares identical pinout and electrical characteristics with the MAX4199ESA (SO-8). Both variants support the same PCB footprint, allowing drop-in replacement during prototyping or cost optimization, while the µMAX version offers superior thermal performance and space savings in compact layouts.
