Description

MAX412ESA is a precision operational amplifier from Maxim Integrated (now part of Analog Devices). It emphasizes high accuracy with very low input offset voltage and low input bias current, plus rail-to-rail input/output for single-supply use. The “ESA” suffix indicates a RoHS-compliant, lead-free version in an 8-pin package (typically MSOP/SOIC). It’s intended for precision signal conditioning, sensor interfaces, instrumentation, and ADC front-end applications where accuracy, low noise, and compact packaging matter. For exact electrical specs (supply ranges, bandwidth, noise, settling, pinout) and packaging details, refer to the official MAX412ESA datasheet.

Features

MAX412ESA is a Maxim precision operational amplifier. Key features (typical):
- Low input offset voltage and drift
- Very low input bias current
- Rail-to-rail input and output
- Unity-gain stable
- Wide supply range (suitable for single-supply operation)
- Low quiescent current
- Low noise
- Adequate slew rate and bandwidth for precision amplification
- Extended temperature range (ESA variant)
- Small 8-pin package (RoHS/SMD)
Note: exact performance specs (numbers) vary by variant; consult the current datasheet for precise values.

Package

8-pin surface-mount package (SO-8/SOP-8).

Pinout

Pin count: 8 pins (8-pin package).
Function: Dual operational amplifier (two op-amps in one package for signal amplification).

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices).
Company type: An American semiconductor company that designs and markets analog and mixed-signal integrated circuits; traditionally fabless (outsourcing fabrication to foundries).

Application

- Precision sensor conditioning (bridge sensors, RTDs, thermocouples)
- Transimpedance/photodiode amplifiers
- Low-noise audio and microphone preamps
- Data-acquisition front ends (ADC drivers) with low offset/drift
- Medical and portable instrumentation
- Industrial sensing and control (current/voltage sensing, signal conditioning)

Equivalent

I can give exact cross‑refs, but I need the device specs. MAX412ESA could refer to different op‑amps/instrumentation amps with varying supplies, bandwidth, and I/O. Please share the datasheet or key specs: supply voltage(s), package, GBW/slew rate, input/output type, and rail-to-rail needs. With those, I’ll provide precise equivalents from TI, Analog Devices, On Semiconductor, etc.
