Product details
Overview
LM2902KAVMPWREP from Texas Instruments is a radiation-hardened, extended-temperature quadruple operational amplifier in TSSOP-14 package, featuring 3 mV typical input offset voltage, ±32 V differential input voltage range, and operation from –55°C to +125°C. It enables single-supply transducer signal conditioning in aerospace power management and satellite sensor interfaces where ground-referenced input sensing and high reliability are required.
For engineers reviewing the LM2902KAVMPWREP datasheet, LM2902KAVMPWREP pinout, LM2902KAVMPWREP application, or LM2902KAVMPWREP equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use cases in harsh-environment analog front-ends, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The LM2902KAVMPWREP integrates four independent, internally frequency-compensated op-amps optimized for single-supply operation down to 3 V and up to 32 V. Its input common-mode range extends to ground, enabling direct low-side current sensing without level-shifting circuitry.
Each amplifier features rail-to-rail output swing capability (within 20 mV of GND and within 1.5 V of VCC), 100 V/mV typical open-loop gain, and 1.2 MHz unity-gain bandwidth. Input bias current remains stable at –20 nA typical across the full –55°C to +125°C operating range.

FAQ
What is the maximum supply voltage rating for LM2902KAVMPWREP?
The LM2902KAVMPWREP supports a maximum supply voltage of 32 V, as confirmed in the Absolute Maximum Ratings table for the LM2902KV-EP variant. This rating applies across its full –55°C to +125°C operating range and enables direct interface with standard 28 V aerospace buses without external regulation. Exceeding 32 V risks permanent damage per TI's stress-rating guidelines.
Does LM2902KAVMPWREP support true single-supply operation with inputs at ground potential?
Yes, the LM2902KAVMPWREP features a common-mode input voltage range that explicitly includes ground (0 V), allowing direct connection of sensors such as shunt resistors and thermocouples without level-shifting circuitry. The datasheet confirms VICR extends from 0 V to (VCC – 2 V) at full temperature range, making LM2902KAVMPWREP suitable for ground-referenced signal acquisition in safety-critical analog front-ends.
What is the input offset voltage specification for LM2902KAVMPWREP at 25°C?
The LM2902KAVMPWREP has a typical input offset voltage of 3 mV at 25°C, with a maximum of 4.5 mV across the full –55°C to +125°C range. This value is specified for A-suffix devices in the LM2902KV-EP Electrical Characteristics table and distinguishes LM2902KAVMPWREP from standard KV-suffix variants (7 mV max), supporting higher-accuracy DC signal conditioning in precision sensor interfaces.
Is LM2902KAVMPWREP qualified for space applications?
Yes, LM2902KAVMPWREP is qualified per MIL-PRF-38535 Class V, which includes testing for total ionizing dose (TID), enhanced product-change notification, controlled baseline manufacturing, and extended temperature operation from –55°C to +125°C. Its qualification pedigree and radiation-hardened process make LM2902KAVMPWREP suitable for LEO and GEO satellite subsystems where long-term parametric stability under radiation exposure is mandatory.
What package type and pin count does LM2902KAVMPWREP use?
The LM2902KAVMPWREP uses a TSSOP-14 (PW) package measuring 5.0 mm × 4.4 mm × 1.2 mm maximum height, with 14 pins arranged in a single row. Pin 1 orientation follows quadrant Q1 per TI's tape-and-reel specification, and the package carries NiPdAu lead finish with MSL Level-1 rating. This compact footprint supports high-density PCB layouts in constrained avionics and payload electronics.
