Product details
Overview
The MAX4074CAESA from Maxim Integrated is a micropower, fixed-gain, rail-to-rail operational amplifier in SOT23-5 package, featuring factory-trimmed internal resistors for 0.1% gain accuracy, ±17V input fault protection, 34µA supply current, and operation from +2.5V to +5.5V single supply - used in low-side current-sense amplification and photodiode preamplification.
For engineers reviewing the MAX4074CAESA datasheet, MAX4074CAESA pinout, MAX4074CAESA application, or MAX4074CAESA equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative parts with documented differences, and supply-chain support for production deployment.
Technical Context
The MAX4074CAESA integrates a precision rail-to-rail op amp core with laser-trimmed on-chip feedback resistors (RF/RG), enabling fixed noninverting or inverting gains without external components. Its decompensated architecture delivers up to 4MHz GBW at AV = +25V/V to +101V/V while maintaining stability with ≤100pF capacitive loads.
Input fault protection uses back-to-back SCR structures and diode clamps with 5kΩ series resistance on IN+ and RG on IN−, limiting input fault current to <3.5mA at ±17V overvoltage. The device operates across –40°C to +70°C and supports single-supply biasing via resistor dividers for AC-coupled configurations.
Key Specifications

FAQ
What is the exact gain configuration of the MAX4074CAESA?
The MAX4074CAESA is a fixed noninverting amplifier with a gain of +2.5V/V, as indicated by the "CA" gain code in the Maxim Gain Selector Guide. This value is factory-laser-trimmed into the on-chip RF/RG resistor network and guaranteed to ±0.1% accuracy across temperature and supply voltage. The MAX4074CAESA does not support reconfiguration - its gain is permanently set at +2.5V/V.
Does the MAX4074CAESA support dual-supply operation?
Yes, the MAX4074CAESA supports dual-supply operation from ±1.25V to ±2.75V, in addition to its primary +2.5V to +5.5V single-supply range. When operated with dual supplies, VEE connects to the negative rail and VCC to the positive rail; the input common-mode range extends from 150mV below VEE to within 1.2V of VCC, enabling ground-referenced signal coupling in both inverting and noninverting configurations.
What is the maximum capacitive load the MAX4074CAESA can drive without oscillation?
The MAX4074CAESA is specified stable with capacitive loads up to 100pF without requiring an isolation resistor. This is confirmed in the Electrical Characteristics table under "Capacitive Load Stability" and validated in Figures 9 and 10 of the datasheet showing clean small-signal pulse response at 47pF and 100pF. Driving >100pF requires adding a series isolation resistor (e.g., 100Ω) between OUT and the load to maintain phase margin.
How does the ±17V input fault protection work on the MAX4074CAESA?
The MAX4074CAESA implements ±17V input fault protection using back-to-back SCR structures at both IN+ and IN− pins, combined with diode clamps to VCC and VEE. A 5kΩ resistor limits current into IN+, while the internal RG resistor limits current into IN−. At ±17V overvoltage, total input current remains below 3.5mA - preventing damage to the IC or upstream signal source while avoiding output phase reversal or latch-up.
Can the MAX4074CAESA be used in a single-supply photodiode transimpedance configuration?
No - the MAX4074CAESA is a fixed-gain voltage amplifier, not a transimpedance amplifier. It lacks the internal feedback path required to convert photodiode current to voltage. However, it can serve as the second-stage gain block after a discrete transimpedance stage, leveraging its +2.5V/V noninverting gain, rail-to-rail output, and 34µA quiescent current to boost and buffer the TIA's output voltage for ADC interfacing.
