Product details
Overview
LM2902KAVQPWRG4Q1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier optimized for low-voltage (2.7 V to 5.5 V), 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 rail-to-rail input common-mode range including ground - enabling precision single-supply current sensing in HEV/EV motor control and ADAS powertrain modules.
For engineers reviewing the LM2902KAVQPWRG4Q1 datasheet, LM2902KAVQPWRG4Q1 pinout, LM2902KAVQPWRG4Q1 application, or LM2902KAVQPWRG4Q1 equivalent, this page provides verified technical context, validated pin functions, real-world automotive use cases, and confirmed alternative options for design-in and BOM continuity planning.
Technical Context
The LM2902KAVQPWRG4Q1 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 stable architecture supports low-side current-sensing configurations without external compensation.
Designed for automotive-grade reliability, it operates across –40°C to +125°C with 2-kV HBM / 1-kV CDM ESD rating and meets AEC-Q100 Grade 1 requirements. Electrical characteristics - including open-loop gain (110 dB min at 2.7 V), PSRR (80 dB min), and CMRR (84 dB min) - are fully specified over temperature and supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into 3.3 V and 5 V automotive domains without level-shifting. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤1% error in 100 mV shunt-based current sensing at room temperature. |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop response up to ~100 kHz for fast transient detection in motor control feedback loops. |
| Quiescent Current | 90 µA per channel - allows four amplifiers to operate continuously on <360 µA total, critical for always-on ADAS subsystems. |
| Input Common-Mode Range | V– to (V+ − 1 V) - permits true single-supply operation with inputs referenced to ground, e.g., low-side shunt monitoring. |
| Output Voltage Swing | 40 mV above V– / 1 V below V+ (min, −40°C to 125°C) - delivers usable dynamic range in 3.3 V systems with 3.2 V headroom. |
| ESD Rating | 2 kV HBM, 1 kV CDM - exceeds AEC-Q100 stress test requirements for robustness in manufacturing and field environments. |
Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm body size), RoHS-compliant, lead-free, moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT1–OUT4) | Amplifier output stages - each drives ≥2 kΩ load with 40 mV–1 V swing margin under full temperature range. |
| 2, 6, 9, 13 | Inverting Input (IN1−–IN4−) | Differential input nodes - accept signals down to V–, enabling ground-referenced sensor interfaces. |
| 3, 5, 10, 12 | Noninverting Input (IN1+–IN4+) | Differential input nodes - support common-mode voltages up to (V+ − 1 V) without performance degradation. |
| 4 | Positive Supply (V+) | Main power rail - must be decoupled with 0.1 µF capacitor placed ≤2 mm from pin per layout guidelines. |
| 11 | Negative Supply (V−) | Ground reference or negative rail - serves as return path for all four channels and internal bias circuitry. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902LVQDRQ1 | SOIC-14 package (8.65 mm × 3.91 mm); 115.1°C/W RθJA; identical electrical specs. | Better thermal dissipation in high-power-density layouts; requires larger PCB footprint than TSSOP. | Select when board space permits and junction temperature rise must stay <25°C at 100% duty cycle. |
| TSV914IQDT | Higher GBW (8 MHz), lower VOS (±0.3 mV), but only 125°C max operating temperature and no AEC-Q100 Grade 1 certification. | Suitable for non-safety-critical infotainment sub-systems; not qualified for powertrain or ADAS deployment. | Choose only for cost-optimized consumer-tier automotive accessories where AEC-Q100 Grade 1 is not mandated. |
Compared with LM2902KAVQPWRG4Q1, LM2902LVQDRQ1 offers superior thermal performance in SOIC packaging but increases board area by 110%, while TSV914IQDT trades automotive qualification and thermal robustness for higher speed and precision in non-safety applications.

FAQ
What is the maximum operating temperature for LM2902KAVQPWRG4Q1?
The LM2902KAVQPWRG4Q1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Junction temperature must remain ≤150°C under all conditions, with thermal data confirming RθJA = 135.3°C/W for the TSSOP-14 package at standard JEDEC 2-layer board conditions.
Does LM2902KAVQPWRG4Q1 support single-supply operation with ground-referenced inputs?
Yes. The LM2902KAVQPWRG4Q1 features a common-mode input voltage range extending to V– (ground in single-supply mode) and up to (V+ − 1 V), enabling direct interface with shunt resistors, thermistors, and other ground-referenced sensors without level-shifting circuitry.
What is the overload recovery time specification for LM2902KAVQPWRG4Q1?
The LM2902KAVQPWRG4Q1 has a typical overload recovery time of 1 µs, defined as the duration required for the output to return from saturation to linear operation after overdrive. This parameter is fully characterized across –40°C to +125°C and supports fast fault detection in motor control safety loops.
Is LM2902KAVQPWRG4Q1 pin-compatible with legacy LM2902-Q1 devices?
No. While functionally similar, LM2902KAVQPWRG4Q1 uses the TSSOP-14 package (PW suffix) with different pin spacing and thermal pad configuration versus the SOIC-14 (D suffix) used by LM2902-Q1. PCB layout and thermal design must be re-validated for the 4.40 mm × 5.00 mm TSSOP footprint.
What decoupling capacitance is recommended for LM2902KAVQPWRG4Q1 power pins?
Texas Instruments specifies a minimum 0.1 µF ceramic capacitor placed within 2 mm of each V+ (pin 4) and V− (pin 11) terminal, connected directly to low-inductance ground planes. Additional bulk capacitance (e.g., 4.7 µF tantalum) may be added at the board-level power entry point for transient suppression.
