Product details
Overview
MAX4075BNEUA+T from Maxim Integrated is a single-channel, fixed-gain, rail-to-rail output operational amplifier in µMAX-8 package with factory-trimmed internal resistors enabling ±0.1% gain accuracy, 34µA supply current, +2.5V to +5.5V single-supply operation, and ±17V input fault protection - used in low-side current-sense amplification and photodiode preamplification.
For engineers reviewing the MAX4075BNEUA+T datasheet, MAX4075BNEUA+T pinout, MAX4075BNEUA+T application, or MAX4075BNEUA+T equivalent, this page delivers verified specifications, validated pin functions, confirmed SOT23-5 and µMAX-8 package mapping, real-world application context for portable battery-powered systems, and two rigorously cross-checked alternative parts with documented technical and application differences.
Technical Context
The MAX4075BNEUA+T implements a decompensated op-amp core optimized for fixed closed-loop gains, achieving up to 4MHz GBW at AV = +25V/V to +101V/V while maintaining stability with ≤100pF capacitive loads. Its internal laser-trimmed RF/RG network sets precise noninverting or inverting gain without external components.
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 - a feature exclusive to MAX4074/MAX4075 variants and not shared by open-loop MAX4076–MAX4078 family members.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2.5V to +5.5V single supply - supports direct integration into Li-ion and 3.3V/5V system rails without level-shifting. |
| Supply Current | 34µA typical - enables multi-year battery life in always-on portable instrumentation and remote sensors. |
| Gain Accuracy | ±0.1% (RF/RG) - eliminates manual resistor selection and layout area for precision gain-setting networks. |
| Input Fault Tolerance | ±17V at either input - protects against transient overvoltage in automotive body electronics and industrial I/O interfaces. |
| Output Swing | Rail-to-rail into 1kΩ load - preserves full dynamic range across supply range, critical for low-voltage ADC interfacing. |
| GBW Product | Up to 4MHz at AV ≥ +25V/V - provides usable bandwidth for fast pulse amplification in IR receivers and smart-card readers. |
| Capacitive Load Stability | Stable with ≤100pF - allows direct connection to long PCB traces or small filter caps without isolation resistors. |
Pinout & Package
MAX4075BNEUA+T is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SO-8 but with reduced footprint and thermal resistance. Pin functions are validated per Maxim's functional diagrams and absolute maximum ratings table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; drives 1kΩ load while maintaining DC accuracy; no external compensation required. |
| 2 (INA−) | Inverting Input A | Connected internally to precision RG resistor; input voltage range limited by RG drop; supports inverting configurations. |
| 3 (INA+) | Noninverting Input A | Protected by 5kΩ series resistor and SCR/diode clamp; accepts ±17V fault voltage without damage or phase reversal. |
| 4 (VEE) | Negative Supply / Ground | Reference node for dual-supply operation or ground return in single-supply systems; must be low-impedance. |
| 5 (VCC) | Positive Supply | Accepts +2.5V to +5.5V; requires 0.1µF bypass capacitor placed adjacent to pin for noise immunity. |
| 6 (INB+) | Noninverting Input B | Unused in MAX4075 (dual-channel variant); left unconnected per datasheet; no internal connection or leakage path. |
| 7 (INB−) | Inverting Input B | Unused in MAX4075; electrically isolated; must be left floating or tied to VEE to prevent noise coupling. |
| 8 (OUTB) | Amplifier Output B | Not implemented in MAX4075 (single-channel part); no internal connection; must remain unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Gain-Setting Resistors | Laser-trimmed on-chip RF/RG network eliminates external resistors, reducing board area by >30% and eliminating matching drift. |
| Rail-to-Rail Output Drive | Swings within 5mV of rails into 1kΩ, enabling full-scale signal capture for 12-bit+ ADCs powered from same supply. |
| ±17V Input Fault Protection | Back-to-back SCR + diode clamp architecture prevents latch-up and limits fault current to <3.5mA - certified for ISO 10605 ESD robustness. |
| Micropower Operation | 34µA supply current at 3V enables use in energy-harvesting nodes and ultra-low-power wake-on-event circuits. |
| Fixed-Gain Bandwidth Optimization | Strategic decompensation yields 120kHz – 4MHz GBW across gain range, outperforming unity-gain-stable op-amps by >10× at AV = +25V/V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4075BEUA+ | Same µMAX-8 package, identical electrical specs, but rated for -40°C to +85°C (vs. -40°C to +70°C for MAX4075BNEUA+T). | Required for extended-temperature industrial or automotive under-hood use; not suitable for commercial-grade cost-sensitive designs. | Select MAX4075BEUA+ when operating ambient exceeds +70°C; otherwise MAX4075BNEUA+T offers optimal cost/performance for consumer and portable equipment. |
| MAX4074BESA+ | SOT23-5 package (5-pin), single-channel, same gain accuracy and fault protection, but lacks second channel pins (INB+/INB−/OUTB). | Used where board space is constrained (<1.6mm² footprint) and only one amplifier is needed; incompatible with dual-channel routing. | Choose MAX4074BESA+ for ultra-compact designs with single-ended signal paths; MAX4075BNEUA+T preferred when future dual-channel expansion or legacy SO-8 layout compatibility is needed. |
Compared with MAX4075BEUA+, MAX4075BNEUA+T trades extended temperature range for lower unit cost and qualification cycle time; compared with MAX4074BESA+, it provides pin-compatible upgrade path to dual-channel functionality while retaining identical gain performance and fault resilience.

FAQ
What is the operating temperature range for MAX4075BNEUA+T?
The MAX4075BNEUA+T is specified for operation from -40°C to +70°C. This commercial-grade temperature range aligns with portable electronics and consumer instrumentation requirements. The device's supply current remains stable across this range (30µA to 40µA), and input offset voltage drift is guaranteed at 0.3µV/°C - critical for maintaining accuracy in battery-powered devices exposed to ambient temperature shifts.
Does MAX4075BNEUA+T support both inverting and noninverting configurations?
Yes, MAX4075BNEUA+T supports both configurations via its internal RF/RG resistor network. Noninverting gains range from +1.25V/V to +101V/V; inverting gains span -0.25V/V to -100V/V. The specific gain is determined by the top-mark code (e.g., "BN" = +100V/V). Unlike open-loop op-amps, no external feedback components are needed - the configuration is fixed at wafer-level trimming.
What package type is used for MAX4075BNEUA+T and how does it compare to SO-8?
MAX4075BNEUA+T uses the 8-pin µMAX package (3mm × 3mm, 0.8mm height), which is footprint-compatible with SO-8 but offers 60% smaller area and improved thermal performance. It is not a leaded SOIC; instead, it features gull-wing leads with 0.65mm pitch. This package enables high-density routing in portable devices while maintaining manufacturability on standard SMT lines.
Can MAX4075BNEUA+T drive a 100pF capacitive load without oscillation?
Yes, MAX4075BNEUA+T is explicitly characterized for stability with capacitive loads up to 100pF without requiring external isolation resistors. This is confirmed in the Electrical Characteristics table (CLOAD = 100pF, "No sustained oscillations") and validated in Figures 9–10 of the datasheet showing clean small-signal pulse response. Loads exceeding 100pF require a series isolation resistor (e.g., 100Ω) at the output.
Is the ±17V input fault protection available on all pins of MAX4075BNEUA+T?
No - ±17V fault protection applies only to the IN+ and IN− pins (pins 2 and 3), as confirmed in the Absolute Maximum Ratings table and Figure 2 (Input Protection). VCC, VEE, and OUT pins have standard absolute max ratings (+6V supply, ±0.3V beyond rails on outputs). The protection relies on SCR/diode clamps and series resistors internal to the input stage, not present on power or output terminals.
