Product details
Overview
The MAX4075AGESA from Maxim Integrated is a single-channel, fixed-gain, rail-to-rail output operational amplifier in SOT23-5 package, featuring factory-trimmed internal resistors for 0.1% gain accuracy, ±17V input fault protection, and operation from +2.5V to +5.5V supply with only 34µA quiescent current. It delivers noninverting gains up to +101V/V and supports low-side current-sense and photodiode preamplifier applications.
For engineers reviewing the MAX4075AGESA datasheet, MAX4075AGESA pinout, MAX4075AGESA application, or MAX4075AGESA equivalent, this page provides verified technical context, key specifications including gain accuracy, supply current, input fault tolerance, GBW, and output swing, plus real-world application mapping and validated alternative options.
Technical Context
The MAX4075AGESA integrates a micropower rail-to-rail op amp core with laser-trimmed on-chip feedback resistors (RF/RG), enabling precise fixed noninverting or inverting gain configurations without external components. Its decompensated architecture delivers up to 4MHz gain-bandwidth product at AV = +25V/V to +101V/V, optimized across five gain bands per the Gain Selector Guide.
Input stage includes back-to-back SCR structures and diode clamps with 5kΩ series resistance on IN+ and RG on IN−, limiting fault current to <3.5mA under ±17V overvoltage. Output drives 1kΩ loads rail-to-rail while maintaining DC accuracy, and remains stable with capacitive loads ≤100pF without isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - Enables direct integration into 3.3V and 5V systems without level-shifting. |
| Quiescent Supply Current | 34µA - Supports battery-powered designs with multi-year operating life. |
| Gain Accuracy | ±0.1% - Eliminates need for external trimming or calibration in precision gain stages. |
| Input Fault Tolerance | ±17V - Protects against transient overvoltage in automotive or industrial sensor interfaces. |
| Gain-Bandwidth Product | Up to 4MHz - Delivers usable bandwidth at high closed-loop gains (e.g., 120kHz at AV = +25V/V). |
| Rail-to-Rail Output Swing | Drives 1kΩ load to within 25mV of rails - Maximizes dynamic range in single-supply signal chains. |
| Capacitive Load Stability | Stable up to 100pF - Allows direct connection to ADC inputs or long PCB traces without compensation. |
Pinout & Package
SOT23-5 package with exposed pad (thermal enhancement not specified); 5-pin surface-mount footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier Output | Delivers rail-to-rail voltage swing into 1kΩ; connects directly to downstream ADC or comparator. |
| 2: VEE | Negative Supply / Ground | Reference node for single-supply operation (typically 0V); must be decoupled with 0.1µF capacitor. |
| 3: IN+ | Noninverting Input | High-impedance input (1000MΩ) with ±17V fault protection; used for reference-biased sensing. |
| 4: IN− | Inverting Input | Connected internally to RG resistor; accepts differential or single-ended signals with 80kΩ input resistance. |
| 5: VCC | Positive Supply | Accepts +2.5V to +5.5V; requires local 0.1µF bypass to VEE for noise immunity. |

Applications
| Low-Side Current Sensing | Photodiode Preamp |
|---|---|
Use Scenario: Monitoring motor phase current in portable power tools using shunt resistor below ground-referenced load. IC Role / Device Role / Timing Role: Noninverting amplifier with fixed +25V/V gain, rejecting common-mode voltage while amplifying µV-level shunt drops. Use Value: ±0.1% gain accuracy ensures ±0.5% current measurement error; ±17V fault tolerance prevents latch-up during load dump events. | Use Scenario: Converting weak photocurrent from IR receiver diode into measurable voltage for microcontroller ADC sampling. IC Role / Device Role / Timing Role: Transimpedance amplifier configured as inverting gain stage (e.g., −100V/V) with low input bias current (≤1nA). Use Value: 200pA max input bias current minimizes dark-current error; 34µA supply current extends battery life in remote controls. |

IC Role / Device Role / Timing Role: High-speed inverting amplifier (AV = −10V/V) with 120kHz −3dB bandwidth and minimal settling time (60µs to 0.01%). Use Value: 4MHz GBW enables clean pulse amplification without overshoot; SOT23-5 footprint saves space in compact scanner housing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4074AESA | Single-channel, same SOT23-5 package and ±17V fault protection, but offers inverting-only fixed gains (e.g., −10V/V). | Preferred where signal inversion is required (e.g., active filter stages), not suitable for noninverting configurations. | Select MAX4074AESA only when inverting topology matches system architecture and gain code is available in Gain Selector Guide. |
| AD8236ARMZ | Zero-drift instrumentation amplifier in MSOP-8; 1.5V/V fixed gain, 120µA supply current, no ±17V fault rating. | Better offset drift (0.1µV/°C) but lacks fault protection and consumes >3× more current; requires external resistors for gain adjustment. | Choose AD8236ARMZ only for ultra-low-drift medical sensor front-ends where fault tolerance is managed externally. |
Compared with MAX4074AESA and AD8236ARMZ, the MAX4075AGESA uniquely combines noninverting gain flexibility, ultra-low power, and integrated ±17V fault protection in a space-constrained SOT23-5 package-making it optimal for portable industrial sensors and battery-powered optical receivers.

FAQ
What is the maximum noninverting gain supported by the MAX4075AGESA?
The MAX4075AGESA supports noninverting gains from +1.25V/V to +101V/V, as defined in the Gain Selector Guide. The specific gain is determined by the top-mark code (e.g., "AG" = +2.25V/V, "BE" = +25V/V). The MAX4075AGESA datasheet confirms these values are factory-trimmed and guaranteed across temperature.
Does the MAX4075AGESA require external gain-setting resistors?
No. The MAX4075AGESA integrates laser-trimmed on-chip RF and RG resistors, eliminating all external gain-setting components. This reduces PCB area, improves thermal tracking, and ensures 0.1% gain accuracy without user calibration - a core feature of the GainAmp™ architecture.
Can the MAX4075AGESA operate from a 3.3V supply?
Yes. The MAX4075AGESA operates from +2.5V to +5.5V, making it fully compatible with standard 3.3V logic and power domains. At VCC = 3.3V, it maintains rail-to-rail output swing, 34µA supply current, and specified gain accuracy - confirmed in the Electrical Characteristics table.
What is the purpose of the N.C. pin in the MAX4075 pinout?
The MAX4075 is an 8-pin SO/µMAX device; its pin 6 and pin 7 are marked N.C. (No Connection) and are not internally bonded. These pins must remain unconnected in layout. The MAX4075AGESA variant uses the SO-8 package, and the N.C. pins are electrically isolated - no pull-up, pull-down, or routing is permitted.
Is the MAX4075AGESA pin-compatible with the MAX4074 series?
No. The MAX4075AGESA is an 8-pin SO device, while the MAX4074 is offered in SOT23-5 and SO-8 variants with different pinouts (e.g., MAX4074 SO-8 has N.C. on pins 2,3,6,7; MAX4075 SO-8 uses pins 2–4 and 6–8 for dual-channel I/O). Direct substitution requires PCB redesign - consult the Pin Configurations section of the MAX4074–MAX4078 datasheet.
