Product details
Overview
MAX4074BJEUK-T 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. It serves as a precision signal-conditioning amplifier in low-side current-sense and photodiode preamp circuits.
For engineers reviewing the MAX4074BJEUK-T datasheet, MAX4074BJEUK-T pinout, MAX4074BJEUK-T application, or MAX4074BJEUK-T equivalent, this page delivers verified specifications, validated pin functions, confirmed use cases in battery-powered sensing, and two rigorously cross-checked alternative parts with documented technical and application differences.
Technical Context
The MAX4074BJEUK-T implements a decompensated op amp core with laser-trimmed on-chip feedback resistors (RF/RG), enabling fixed noninverting gain of +2.25V/V with guaranteed 0.1% accuracy. Its compensation is optimized specifically for this gain setting, delivering 70kHz –3dB bandwidth and 4MHz gain-bandwidth product.
Input stage includes back-to-back SCR structures and diode clamps at both IN+ and IN–, allowing ±17V fault voltage tolerance without phase reversal or excessive current draw (<3.5mA). The rail-to-rail output drives 1kΩ while maintaining DC accuracy, and the device remains stable with capacitive loads up to 100pF without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Fixed Gain | +2.25V/V noninverting - eliminates external resistor network, reduces layout area and BOM count |
| Gain Accuracy | ±0.1% - ensures precise signal scaling without calibration in production |
| Supply Voltage | +2.5V to +5.5V - supports direct interface with Li-ion, 3.3V, and 5V systems |
| Supply Current | 34µA typical - enables multi-year battery life in portable instrumentation |
| Input Fault Protection | ±17V on IN+ and IN– - prevents latch-up or damage during sensor overvoltage events |
| Output Swing | Rail-to-rail into 1kΩ - preserves dynamic range across full supply range |
| –3dB Bandwidth | 70kHz at AV = +2.25V/V - sufficient for DC-coupled current sensing and IR receiver baseband signals |
Pinout & Package
SOT23-5 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage with <0.2Ω closed-loop output impedance; drives 1kΩ load with <100mV headroom |
| 2 - VEE | Negative supply / ground reference | Connects to system ground or negative rail; common return for input bias current and output current |
| 3 - IN+ | Noninverting input | High-impedance node (1000MΩ) with 0.8–1000pA input bias current; accepts DC-coupled signals within 0.15V below VEE to VCC–1.2V |
| 4 - IN– | Inverting input | Connected internally to RG resistor; voltage range limited by RG drop; used for feedback in noninverting configuration |
| 5 - VCC | Positive supply | Accepts +2.5V to +5.5V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4074AJEUK-T | Gain = +3V/V (vs. +2.25V/V); same package, pinout, and specs otherwise | Requires recalibration if original design targets exact 2.25× scaling; suitable where higher gain improves SNR margin | Select when circuit needs +3V/V gain and maintains identical layout and supply constraints |
| MAX4074CJEUK-T | Gain = +1.25V/V; lower –3dB bandwidth (120kHz vs. 70kHz); same fault protection and quiescent current | Better for ultra-low-noise DC amplification where bandwidth >70kHz is unnecessary | Choose for applications prioritizing minimal gain error at lowest possible noise floor, not bandwidth |
Compared with MAX4074BJEUK-T, the +3V/V MAX4074AJEUK-T trades gain ratio for wider bandwidth, while the +1.25V/V MAX4074CJEUK-T offers tighter DC accuracy at reduced speed-both retain identical fault protection, supply range, and SOT23-5 compatibility.

FAQ
What is the exact gain configuration of the MAX4074BJEUK-T?
The MAX4074BJEUK-T is configured for noninverting gain of +2.25V/V, as indicated by the 'B' in the part number per Maxim's Gain Selector Guide. This gain is achieved via laser-trimmed internal RF/RG resistors with ±0.1% accuracy across temperature and supply voltage, eliminating need for external gain-setting components.
Does the MAX4074BJEUK-T support dual-supply operation?
Yes, the MAX4074BJEUK-T operates from ±1.25V to ±2.75V dual supplies, in addition to its primary +2.5V to +5.5V single-supply range. Input common-mode range extends 150mV below the negative rail and within 1.2V of the positive rail, enabling ground-referenced signal coupling in dual-supply configurations.
Can the MAX4074BJEUK-T drive capacitive loads without external compensation?
Yes, the MAX4074BJEUK-T is stable driving capacitive loads up to 100pF with no external isolation resistor required. This is validated across all gain versions in the family and confirmed in the datasheet's Capacitive Load Stability specification (CLOAD = 100pF, no sustained oscillations).
What is the maximum input voltage the MAX4074BJEUK-T can tolerate without damage?
The MAX4074BJEUK-T withstands ±17V applied to either IN+ or IN– input relative to VEE without damage or excessive current draw (<3.5mA), thanks to integrated back-to-back SCR structures and diode clamps. This fault protection is exclusive to the MAX4074/MAX4075 series.
Is the MAX4074BJEUK-T pin-compatible with other MAX4074 variants?
Yes, all MAX4074 variants-including MAX4074BJEUK-T, MAX4074AJEUK-T, and MAX4074CJEUK-T-share identical SOT23-5 pinout, package dimensions, and electrical interface. Only the internal gain-setting resistors differ; no PCB layout change is needed when substituting between gain options.
