Product details
Overview
MAX4199ESA 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 MAX4199ESA datasheet, MAX4199ESA pinout, MAX4199ESA application, or MAX4199ESA equivalent, key selection criteria include guaranteed 0.01% gain error over temperature, Beyond-the-Rails™ input range compatibility (VEE −0.1V to VCC −1.0V), shutdown current of 6.5µA, and µMAX-8 package suitability for space-constrained battery-powered instrumentation.
Technical Context
The MAX4199ESA integrates factory-trimmed thin-film resistors to achieve ±0.01% gain accuracy at +10V/V, with gain temperature coefficient of ±1ppm/°C. Its input stage supports common-mode voltages from VEE −0.1V to VCC −1.0V, enabling direct sensing of signals below ground in single-supply systems.
The rail-to-rail output stage delivers 45kHz −3dB bandwidth while sinking/sourcing into 5kΩ loads, and features active-low SHDN control referenced to VCC (VIH = VCC −1.5V, VIL = VCC −2.5V), with 35µs enable/disable settling time and high-impedance output in shutdown.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA199A1IDBVR | Single-supply, +50V/V fixed gain, 100dB CMR, 50µA supply current, SOT-23-6 package | Higher gain and wider common-mode range (−0.2V to +26V), but lower CMR and no Beyond-the-Rails input capability | Select for high-side current sensing where wide input common-mode is required, not for sub-rail signal capture |
| AD8276ARMZ | Unity-gain stable, +0.5V/V to +100V/V programmable gain, 80dB CMR, 275µA supply current, MSOP-8 package | Adjustable gain and higher bandwidth (550kHz), but 27× higher supply current and reduced DC precision | Select when gain flexibility or AC response matters more than micropower or DC accuracy |
Compared with INA199A1IDBVR and AD8276ARMZ, the MAX4199ESA uniquely combines micropower operation (42µA), 110dB DC CMR, and sub-rail input capability-making it irreplaceable for ultra-low-power, high-precision differential measurement where input signals extend below ground in single-supply systems.

FAQ
What is the maximum input common-mode voltage range for MAX4199ESA?
The MAX4199ESA supports an input common-mode voltage range from VEE −0.1V to VCC −1.0V at +5V supply. This allows the device to accurately amplify signals that fall slightly below ground-such as those from grounded shunt resistors-without phase reversal or CMR degradation. The range scales with supply voltage, maintaining VEE −0.1V lower bound and VCC −1.0V upper bound across the full +2.7V to +7.5V operating range.
Does MAX4199ESA require external gain-setting resistors?
No, the MAX4199ESA does not require external gain-setting resistors. It integrates factory-trimmed thin-film resistors to deliver a precise, fixed +10V/V gain with ±0.01% maximum error over −40°C to +85°C. This eliminates resistor matching tolerances, thermal drift, and board area associated with discrete gain networks-ensuring consistent performance across production units and temperature.
How does the shutdown function operate on MAX4199ESA?
The MAX4199ESA features an active-low SHDN pin referenced to VCC-not ground-with VIH = VCC −1.5V and VIL = VCC −2.5V. Pulling SHDN to VEE or ≤VCC −2.5V places the device in shutdown, reducing supply current to 6.5µA max and placing the OUT pin in high-impedance state. Exit time from shutdown is 35µs, and the pin draws only ±0.1µA bias current, simplifying drive from microcontroller GPIOs.
Can MAX4199ESA drive capacitive loads, and what is its stability limit?
Yes, the MAX4199ESA is designed to drive capacitive loads up to 590pF without external compensation, as verified in its Typical Operating Characteristics. For larger loads (e.g., >600pF), a series isolation resistor (15Ω–100Ω) between OUT and CL restores stability at the cost of minor bandwidth reduction. The device remains stable with 590pF directly on the output, making it suitable for driving ADC input capacitance or long PCB traces without added components.
What is the output voltage swing specification for MAX4199ESA under load?
The MAX4199ESA delivers rail-to-rail output swing: VEE + 0.02V to VCC − 0.02V into a 25kΩ load, and VEE + 0.2V to VCC − 0.2V into a 5kΩ load at +5V supply. This means it can drive a 5kΩ load to within 200mV of each rail-enabling full utilization of a 12-bit ADC's input range in single-supply 3.3V or 5V systems without external level-shifting circuitry.
