Product details
Overview
TLV2462AQPWRG4Q1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality, 6.4 MHz gain-bandwidth product, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current. It operates from 2.7 V to 6 V and is qualified for HEV/EV powertrain and battery management systems.
For engineers reviewing the TLV2462AQPWRG4Q1 datasheet, TLV2462AQPWRG4Q1 pinout, TLV2462AQPWRG4Q1 application, or TLV2462AQPWRG4Q1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), rail-to-rail output swing with high-current capability, micropower shutdown mode (0.3 μA/channel), low input offset voltage (150 μV typ), and TSSOP-8 packaging for space-constrained automotive modules.
Technical Context
The TLV2462AQPWRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for low-voltage, high-dynamic-range signal conditioning in safety-critical automotive subsystems. Its input common-mode range extends 0.2 V beyond both rails, enabling full-scale operation at 3 V single-supply.
Each channel features independent shutdown control (SHDN pin), placing the output in high-impedance state while reducing supply current to 0.3 μA per channel. The amplifier maintains 6.4 MHz bandwidth and 45° phase margin under 160 pF capacitive load, supporting stable buffering of SAR ADC inputs and sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - Enables stable unity-gain buffer operation up to ~6 MHz with minimal phase lag. |
| Slew rate | 1.6 V/μs - Supports 10-bit settling of 2-V step signals within 1.83 μs at 0.01% accuracy. |
| Output drive | ±80 mA - Drives 10-mA loads while maintaining rail-to-rail swing at 5 V supply. |
| Supply current (per channel) | 0.55 mA typical at 5 V - Enables dual-channel analog signal path with sub-1.2 mA total quiescent draw. |
| Input offset voltage | 150 μV typical (25°C), 1700 μV max (–40°C to +125°C) - Minimizes DC error in precision current sensing and voltage monitoring. |
| Shutdown current | 0.3 μA per channel - Reduces system standby power by >99.9% versus active mode. |
| Common-mode input range | –0.2 V to VDD + 0.2 V - Accepts inputs below ground or above supply, critical for single-supply sensor interfaces. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input, channel 1 | High-impedance CMOS node; accepts signals from –0.2 V to VDD + 0.2 V. |

| 3 | Output, channel 1 | Rail-to-rail capable; sinks or sources up to ±80 mA while maintaining <0.5 V saturation near rails. |
| 4 | GND | Primary reference for all inputs/outputs; requires low-impedance PCB connection to minimize noise coupling. |
| 5 | Noninverting input, channel 2 | Electrically isolated from channel 1; enables independent dual-sensor conditioning on one die. |
| 6 | Inverting input, channel 2 | Matched to pin 5; supports identical configurations as channel 1 (e.g., transimpedance, difference amp). |
| 7 | Output, channel 2 | Independent output stage; no crosstalk with channel 1 at frequencies ≤1 MHz. |
| 8 | VDD+ | Positive supply rail; accepts 2.7 V to 6 V; bypass capacitor required for stability. |
