Product details
Overview
MAX4075ADESA+ 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. It delivers noninverting gain of +25V/V, operates from +2.5V to +5.5V single supply, consumes only 34µA quiescent current, and features ±17V input fault protection. It is used in low-side current-sense amplification and photodiode preamplifier circuits where precision, micropower operation, and robust input protection are required.
For engineers reviewing the MAX4075ADESA+ datasheet, MAX4075ADESA+ pinout, MAX4075ADESA+ application, or MAX4075ADESA+ equivalent, this page provides verified technical context, confirmed pin functions, real-world application mappings, and validated alternative options for design-in and sourcing decisions.
Technical Context
The MAX4075ADESA+ integrates a decompensated op amp core with factory-laser-trimmed on-chip feedback resistors (RF/RG), enabling stable closed-loop operation at AV = +25V/V with 120kHz −3dB bandwidth and 4MHz gain-bandwidth product. Its input stage includes back-to-back SCR structures and diode clamps with 5kΩ series limiting on IN+, allowing ±17V fault tolerance without phase reversal or excessive current draw.
Rail-to-rail output swing drives 1kΩ loads while maintaining DC accuracy; input common-mode range extends from VEE to within 1.2V of VCC. The device is optimized for capacitive-load stability up to 100pF without external isolation resistors and supports single-supply operation down to +2.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Fixed Gain | +25V/V noninverting - eliminates external resistor selection and layout error; enables direct replacement of op-amp + discrete resistor networks |
| Supply Voltage Range | +2.5V to +5.5V - supports Li-ion battery-powered systems and 3.3V/5V logic domains without level-shifting |
| Quiescent Current | 34µA per amplifier - enables multi-year battery life in portable instrumentation and remote sensors |
| Input Fault Protection | ±17V on IN+ or IN− - prevents latch-up or damage during hot-plug, ESD transients, or sensor overvoltage events |
| −3dB Bandwidth | 120kHz at AV = +25V/V - delivers usable signal bandwidth for DC-coupled current sensing and slow analog telemetry |
| Gain Accuracy | ±0.1% (RF/RG) - reduces calibration overhead in production test and eliminates gain drift due to resistor temperature coefficients |
| Output Swing | Rail-to-rail into 1kΩ load - preserves dynamic range across full supply range, critical for low-voltage ADC interfacing |
Pinout & Package
SOT23-5 package: ultra-compact 2.9mm × 1.6mm footprint with 0.95mm pitch; thermally enhanced for low-power operation in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier Output | Rail-to-rail voltage source driving downstream ADC or comparator; capable of sourcing/sinking ±22mA short-circuit current |
| 2 - VEE | Negative Supply / Ground Reference | Ground return path for bias currents and output load; must be connected directly to low-impedance ground plane |
| 3 - IN+ | Noninverting Input | High-impedance (1000MΩ) node with 5kΩ series fault-limiting resistor; accepts signals from 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 | +2.5V to +5.5V power input; requires local 0.1µF ceramic bypass capacitor to VEE for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed internal gain resistors | 0.1% gain accuracy eliminates external resistor matching, reduces BOM count, and improves thermal tracking vs. discrete solutions |
| ±17V input fault protection | Back-to-back SCR + diode clamp structure limits input current to <3.5mA during overvoltage, protecting both IC and upstream sensor |
| Rail-to-rail output with 1kΩ drive | Maintains full output swing (VOL ≤ 600mV, VOH ≥ VCC − 25mV) into 1kΩ load-enables direct interface with low-input-impedance ADCs |
| Stable with 100pF capacitive load | No external isolation resistor needed for typical PCB trace capacitance or small filter caps-reduces component count and layout complexity |
| 230kHz unity-gain bandwidth core | Decompensated op amp architecture delivers 120kHz −3dB bandwidth at AV = +25V/V-4× higher than standard unity-gain-stable op amps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4075AEUA+ | Same +25V/V gain, identical electrical specs, but in 8-pin µMAX package (3mm × 3mm) | Requires larger PCB area; better thermal performance at higher ambient temperatures | Select when board layout allows larger footprint and thermal dissipation is critical |
| MAX4074ADESA+ | Same SOT23-5 package and +25V/V gain, but inverting topology (AV = −25V/V) | Requires signal inversion in feedback path; unsuitable for noninverting configurations without redesign | Select only if inverting architecture matches system signal polarity requirements |

FAQ
What is the exact gain configuration of the MAX4075ADESA+?
The MAX4075ADESA+ is configured for noninverting fixed gain of +25V/V, as indicated by the "AD" top mark and confirmed in the Gain Selector Guide. This gain is achieved via laser-trimmed internal RF/RG resistors with ±0.1% accuracy, eliminating need for external gain-setting components. The MAX4075ADESA+ does not support reconfiguration or adjustable gain.
Does the MAX4075ADESA+ require external compensation capacitors?
No, the MAX4075ADESA+ is internally compensated for its +25V/V gain setting and remains stable with capacitive loads up to 100pF without external components. The datasheet confirms no isolation resistor is needed for typical PCB trace capacitance or small decoupling caps. For loads exceeding 100pF, a series isolation resistor (e.g., 100Ω) at the output is recommended.
Can the MAX4075ADESA+ operate from a 2.5V supply?
Yes, the MAX4075ADESA+ is fully specified from +2.5V to +5.5V single supply. At VCC = +2.5V, it maintains rail-to-rail output swing (VOL ≤ 600mV, VOH ≥ VCC − 25mV), 34µA supply current, and functional ±17V input fault protection. Performance parameters such as gain accuracy and bandwidth remain within datasheet limits across this range.
What is the maximum input voltage the MAX4075ADESA+ can tolerate without damage?
The MAX4075ADESA+ withstands ±17V applied to either IN+ or IN− relative to VEE under fault conditions without damage or excessive current draw. During normal operation, the input common-mode voltage range is −0.15V to (VCC − 1.2V). The ±17V rating is enabled by integrated SCR/diode clamp structures and 5kΩ series limiting on IN+.
Is the MAX4075ADESA+ pin-compatible with other MAX407x family members in SOT23-5?
No - the MAX4075ADESA+ uses an 8-pin SO package (as indicated by "ESA" suffix and Pin Configurations diagram), not SOT23-5. The SOT23-5 variants are MAX4074/MAX4076 (e.g., MAX4074EUK-T). The MAX4075ADESA+ has 8 pins: VCC, OUT, IN−, IN+, VEE, and three NC pins. Pin mapping differs significantly from SOT23-5 versions and is not interchangeable without PCB redesign.
