Product details
Overview
LM2902KAVQPWREP from Texas Instruments is a radiation-hardened, extended-temperature quadruple operational amplifier optimized for single-supply operation in harsh environments. It features 3 mV typical input offset voltage, ±32 V differential input voltage range, rail-to-rail output swing capability (VOL = 20 mV max at RL ≤10 kΩ), and operates across –40°C to +125°C. It is used in precision sensor signal conditioning within aerospace power management systems.
For engineers reviewing the LM2902KAVQPWREP datasheet, LM2902KAVQPWREP pinout, LM2902KAVQPWREP application, or LM2902KAVQPWREP equivalent, this page delivers verified electrical parameters, TSSOP-14 package layout, real-world use cases in high-reliability analog front-ends, and validated alternative options with documented functional trade-offs.
Technical Context
The LM2902KAVQPWREP integrates four independent, internally frequency-compensated op-amps with common-mode input voltage range extending to ground - enabling direct low-side current sensing. Its input stage supports differential inputs up to ±32 V, and its output stage delivers ±20 mA short-circuit current while maintaining 100 V/mV large-signal voltage gain.
Designed for extended temperature operation (–40°C to +125°C), it uses enhanced plastic packaging qualified per JEDEC standards including HAST, temperature cycling, and intermetallic life testing. ESD protection exceeds 2 kV (HBM), 200 V (MM), and 2 kV (CDM), meeting MIL-STD-883 requirements for space-grade analog circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V - enables direct interface with 5 V, 12 V, or 28 V avionics buses without level-shifting. |
| Input Offset Voltage (TYP) | 1 mV - ensures sub-millivolt DC error in precision transducer amplification over full temperature range. |
| Common-Mode Input Range | 0 V to VCC–2 V - allows ground-referenced sensor inputs (e.g., shunt-based current monitors) without external biasing. |
| Output Voltage Swing (VOL) | 20 mV max at RL ≤10 kΩ - guarantees reliable logic-level compatibility with downstream comparators or ADC drivers. |
| Large-Signal Voltage Gain | 100 V/mV - provides ≥80 dB open-loop gain for stable closed-loop configurations down to unity gain. |
| Supply Current (4 amps) | 0.7–1.2 mA - enables ultra-low-power operation in battery-backed telemetry modules. |

FAQ
What is the maximum supply voltage supported by LM2902KAVQPWREP?
The LM2902KAVQPWREP 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 operating temperature range of –40°C to +125°C and enables direct integration with 28 V avionics buses without external regulation. Exceeding 32 V risks permanent damage per TI's stress-rating guidelines.
Does LM2902KAVQPWREP support true rail-to-rail input operation?
The LM2902KAVQPWREP does not support rail-to-rail input operation - its common-mode input voltage range extends from 0 V to VCC–2 V, meaning the upper limit is 2 V below the positive rail. However, it does include ground in the input range, allowing direct sensing of signals referenced to system ground, which is essential for shunt-based current measurement and other low-side sensing applications.
What is the typical input offset voltage for LM2902KAVQPWREP over temperature?
The LM2902KAVQPWREP has a typical input offset voltage of 1 mV at 25°C and a maximum of 4.5 mV across the full –40°C to +125°C operating range, as specified in the Electrical Characteristics table for A-suffix devices. Its temperature drift is rated at 7 µV/°C, ensuring predictable, bounded drift behavior critical for uncalibrated long-duration deployments.
Is LM2902KAVQPWREP pin-compatible with standard LM2902 variants?
Yes, LM2902KAVQPWREP is pin-compatible with other TSSOP-14 packaged LM2902 variants including LM2902QPWREP and LM2902KAVMPWREP. All share identical pin numbering, function mapping (1OUT–1IN–1IN+–VCC–2IN+–2IN−–2OUT–4OUT–4IN−–4IN+–GND–3IN+–3IN−–3OUT), and mechanical footprint per PW0014A package drawing - enabling drop-in replacement where electrical and reliability requirements align.
What packaging and assembly qualifications apply to LM2902KAVQPWREP?
LM2902KAVQPWREP uses enhanced plastic packaging qualified per JEDEC standards including Highly Accelerated Stress Test (HAST), temperature cycling, autoclave, electromigration, bond intermetallic life, and mold compound life. It carries MSL Level-1 (260°C peak reflow) and RoHS-compliant NiPdAu lead finish, supporting lead-free assembly in high-reliability manufacturing lines without moisture sensitivity concerns.
