Product details
Overview
MAX4075BEESA from Maxim Integrated is a single-channel, fixed-gain, rail-to-rail output operational amplifier with internal laser-trimmed resistors providing ±0.1% gain accuracy at noninverting gain +25V/V. It operates from a +2.5V to +5.5V single supply, draws only 34µA quiescent current, and delivers up to 4MHz gain-bandwidth product. It is used in low-side current-sense amplification and photodiode preamplification where precision, micropower, and fault-protected inputs are critical.
For engineers reviewing the MAX4075BEESA datasheet, MAX4075BEESA pinout, MAX4075BEESA application, or MAX4075BEESA equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternative parts with documented differences, and supply-chain support for industrial and portable electronics designs.
Technical Context
The MAX4075BEESA integrates a decompensated rail-to-rail op amp core with factory-laser-trimmed on-chip feedback resistors (RF/RG) to deliver fixed noninverting gain of +25V/V. Its compensation is optimized specifically for that gain setting, enabling 120kHz –3dB bandwidth and 4MHz GBW - significantly higher than unity-gain-stable equivalents at same gain.
Input fault protection includes back-to-back SCR structures and diode clamps on both IN+ and IN– pins, allowing ±17V input overvoltage relative to VEE without damage or phase reversal. The output drives 1kΩ loads while maintaining rail-to-rail swing and <3.5mV DC offset across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Configuration | Noninverting, fixed +25V/V - eliminates external resistor layout, reduces board area, and guarantees gain accuracy without trimming. |
| Supply Voltage Range | +2.5V to +5.5V - supports direct operation from Li-ion, 3.3V, and 5V rails without regulators. |
| Quiescent Current | 34µA per amplifier - enables multi-year battery life in portable instrumentation and remote sensors. |
| Gain-Bandwidth Product | 4MHz - ensures stable closed-loop response up to 120kHz at AV = +25V/V, suitable for fast pulse amplification. |
| Input Fault Protection | ±17V on IN+ and IN– - protects against ESD, hot-plug transients, and sensor wiring faults without external clamps. |
| Output Swing | Rail-to-rail into 1kΩ - delivers full dynamic range at low supply voltages, preserving SNR in ADC front-ends. |
| Input Offset Voltage | 0.2mV typical - minimizes baseline error in precision current sensing with shunt resistors ≤100mΩ. |
Pinout & Package
SOT23-5 package: compact 2.9mm × 1.6mm footprint, surface-mount, lead-free, rated for –40°C to +70°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; drives 1kΩ load with <25mV headroom at VCC and VEE. |
| 2 - VEE | Negative supply / ground reference | Connects to system ground in single-supply configurations; sets common-mode baseline for input stage. |
| 3 - IN+ | Noninverting input | High-impedance node (1000MΩ); accepts signal referenced to VEE; protected by 5kΩ series resistor and clamp diodes. |
| 4 - IN– | Inverting input | Connected internally to RG; voltage range limited by core op amp's common-mode limits and RG drop; fault-protected. |
| 5 - VCC | Positive supply | Accepts +2.5V to +5.5V; requires local 0.1µF ceramic bypass capacitor to VEE for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed RF/RG network | 0.1% gain accuracy at +25V/V - eliminates calibration and reduces production test time for current-sense modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4075AEASA | Gain +1.25V/V (vs. +25V/V); identical SOT23-5 package, pinout, and fault protection. | Used in high-precision voltage buffering where minimal gain error dominates over bandwidth. | Select when system requires lowest possible input offset drift (0.3µV/°C) and gain accuracy at unity-like settings. |
| INA186AIDRLR | Current-sense amplifier (not op amp); 20V/V fixed gain; 1.8V–5.5V supply; 35µA ICC; no ±17V fault protection. | Optimized for bidirectional shunt sensing with integrated reference; lacks photodiode or general-purpose op amp flexibility. | Choose only for dedicated low-side current sensing with integrated zero-drift architecture - not a drop-in replacement. |
Compared with MAX4075AEASA and INA186AIDRLR, the MAX4075BEESA uniquely balances high fixed gain (+25V/V), wide bandwidth (120kHz), ±17V fault tolerance, and micropower operation - making it optimal for space-constrained, transient-prone sensor front-ends requiring precision amplification without external gain-setting components.

FAQ
What is the exact gain configuration and tolerance of the MAX4075BEESA?
The MAX4075BEESA is a noninverting fixed-gain amplifier with nominal gain of +25V/V. Its gain accuracy is specified at ±0.1% (typical) due to factory laser trimming of internal RF/RG resistors. This value is confirmed in the Electrical Characteristics table under "DC Gain Accuracy" for MAX4074/MAX4075, and applies directly to the BE gain code per the Gain Selector Guide.
Does the MAX4075BEESA support dual-supply operation?
Yes, the MAX4075BEESA supports dual-supply operation from ±1.25V to ±2.75V, as stated in the Applications Information section. However, its pinout (SOT23-5) assigns Pin 2 to VEE (negative supply) and Pin 5 to VCC (positive supply), requiring proper decoupling on both rails. Single-supply use from +2.5V to +5.5V is more common and equally supported.
What is the maximum capacitive load the MAX4075BEESA can drive without oscillation?
The MAX4075BEESA is stable driving capacitive loads up to 100pF without external isolation components, as verified in the "Capacitive Load Stability" specification (CLOAD = 100pF, no sustained oscillations). This is confirmed in both the MAX4074/MAX4075 Electrical Characteristics table and the Applications Information section.
Is the MAX4075BEESA pin-compatible with other devices in the MAX4074–MAX4078 family?
No - the MAX4075BEESA uses an 8-pin SO package (as indicated by "ESA" suffix and Ordering Information table), while the MAX4074 and MAX4076 variants in SOT23-5 have different pinouts and terminal counts. The MAX4075BEESA shares the same 8-pin SO footprint and pin mapping as other MAX4075xx ESA variants, but is not pin-compatible with MAX4074 or MAX4076 families.
What does the "B" in MAX4075BEESA indicate in the gain code?
The "B" in MAX4075BEESA corresponds to the gain code "BE", which selects noninverting gain +25V/V per the Gain Selector Guide (page 15). The guide lists ADJS/BE for +25V/V, confirming that MAX4075BEESA implements precisely that fixed gain configuration with associated bandwidth and accuracy specs.
