Product details
Overview
LM2902KVQPWRG4Q1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier optimized for low-voltage, cost-sensitive systems. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 40 nV/√Hz input voltage noise density, 90 µA per channel quiescent current, and operates from 2.7 V to 5.5 V supply - enabling precision single-supply current sensing in HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the LM2902KVQPWRG4Q1 datasheet, LM2902KVQPWRG4Q1 pinout, LM2902KVQPWRG4Q1 application, or LM2902KVQPWRG4Q1 equivalent, this page provides verified package mapping (TSSOP-14), validated pin functions, confirmed automotive-grade thermal and ESD specs (–40°C to 125°C, 2-kV HBM), and real-world implementation data for low-side current sensing and infotainment signal conditioning.
Technical Context
The LM2902KVQPWRG4Q1 implements a P-channel input differential pair with parallel N-channel stage to eliminate phase reversal during overdrive while maintaining rail-to-rail common-mode input range down to V–. Its unity-gain stability and 75° phase margin at 5.5 V ensure robust performance in feedback configurations without external compensation.
Designed specifically for automotive powertrain and body electronics, it integrates EMI rejection ratio (EMIRR) up to 140 dB across 10 MHz–10 GHz and supports stable operation under noisy battery-supply conditions via internal ESD protection (2-kV HBM, 1-kV CDM) and 0.1-µF local bypassing guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables multi-sensor signal conditioning or cascaded filtering in single-package layout. |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with 3.3 V microcontroller domains and automotive 5 V rails without level-shifting. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤35 mV error in 35× gain current-sense circuits at room temperature. |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop response up to ~100 kHz for 10× gain configurations in motor control loops. |
| Quiescent Current | 90 µA per channel - enables always-on sensor monitoring with <360 µA total system bias in quad configuration. |
| Operating Temperature | –40°C to 125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin-mounted ECUs. |
| ESD Rating | 2-kV HBM, 1-kV CDM - withstands assembly and field handling stresses in automotive manufacturing environments. |

TSSOP-14 package (4.40 mm × 5.00 mm body size) with exposed pad for thermal enhancement; RoHS-compliant, lead-free finish; moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT1–OUT4) | Amplifier outputs capable of sourcing/sinking ±40 mA; swing within 40–75 mV of V– and 1 V of V+ at full temperature range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902QPWRQ1 | Higher input offset voltage (±3 mV typ), same 1 MHz GBW and 90 µA IQ, but rated only to 105°C junction. | Limited to cabin applications (infotainment, lighting); not qualified for under-hood powertrain use. | Select when cost is primary constraint and ambient temperature stays below 85°C. |
| TSV914IQDT | Lower noise (14 nV/√Hz), higher GBW (8 MHz), but higher IQ (130 µA/ch) and narrower supply range (2.7 V–5.5 V same, but no AEC-Q100 Grade 1 cert). | Suitable for high-speed sensor signal chains (e.g., ultrasonic parking assist), but lacks automotive qualification documentation. | Select when bandwidth and noise dominate over qualification rigor and ultra-low power. |
Compared with LM2902QPWRQ1, LM2902KVQPWRG4Q1 adds Grade 1 thermal validation and tighter offset for precision current sensing; compared with TSV914IQDT, it trades speed and noise for guaranteed automotive reliability and lower static power - making it optimal for cost-constrained, thermally demanding ECU subsystems.

FAQ
What automotive qualification level does LM2902KVQPWRG4Q1 meet?
LM2902KVQPWRG4Q1 is AEC-Q100 Grade 1 qualified, meaning it is certified for operation from –40°C to +125°C ambient temperature and has passed stress tests including HTOL, TC, and ESD per JESD22 standards. This makes LM2902KVQPWRG4Q1 suitable for engine bay, transmission, and inverter applications where sustained high-temperature reliability is mandatory.
Does LM2902KVQPWRG4Q1 support true rail-to-rail input operation?
LM2902KVQPWRG4Q1 supports common-mode input voltage range from V– – 0.1 V to V+ – 1 V across its full 2.7 V–5.5 V supply range. While not rail-to-rail on the positive side, this specification enables direct low-side shunt sensing without level shifting - a key design advantage over older op amps that require ≥1.5 V headroom above V–.
Can LM2902KVQPWRG4Q1 be used in single-supply configurations?
Yes, LM2902KVQPWRG4Q1 is explicitly designed for single-supply operation: its input common-mode range includes ground (V–), and output swings within 40–75 mV of V– and 1 V of V+. When powered from 5 V with V– tied to GND, it reliably conditions signals from 0 V to 4 V - ideal for interfacing with 3.3 V ADCs and microcontrollers.
What is the maximum capacitive load LM2902KVQPWRG4Q1 can drive stably?
LM2902KVQPWRG4Q1 maintains ≥75° phase margin and unity-gain stability with up to 100 pF capacitive load, as verified in Figure 6-20 of the datasheet. For loads exceeding 100 pF, TI recommends adding a series resistor (≥10 Ω) between output and capacitance to isolate reactive feedback and preserve stability in motor control or filter applications.
How does LM2902KVQPWRG4Q1 handle input overvoltage conditions?
LM2902KVQPWRG4Q1 features internal ESD diodes clamping inputs to V+ and V– rails. Inputs tolerate voltages from (V–) – 0.5 V to (V+) + 0.5 V continuously, provided input current is limited to ±10 mA. Exceeding these limits risks permanent damage - external series resistors are recommended in high-energy transducer interfaces like piezoelectric knock sensors.
