Product details
Overview
TLC2272QPWRG4Q1 from Texas Instruments is a dual, rail-to-rail output, automotive-grade LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), featuring 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 3.6 V/μs slew rate. It supports single- or split-supply operation up to ±8 V and delivers rail-to-rail output swing for interfacing with ADCs in battery management and engine control systems.
For engineers reviewing the TLC2272QPWRG4Q1 datasheet, TLC2272QPWRG4Q1 pinout, TLC2272QPWRG4Q1 application, or TLC2272QPWRG4Q1 equivalent, this page provides verified specifications, package mapping, functional safety documentation status, real-world automotive use cases, and validated alternative options - all confirmed against TI's SGLS007G datasheet (Rev.

Technical Context
The TLC2272QPWRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for precision signal conditioning in high-impedance sensor interfaces. Its input stage operates down to the negative rail, enabling full common-mode range utilization in single-supply configurations.
It achieves 2.2 MHz gain-bandwidth product and 50° phase margin with 100 pF capacitive load, supporting stable unity-gain buffer and inverting amplifier configurations without external compensation. Functional safety documentation is available specifically for the TLC2272-Q1 variant per ISO 26262 system-level design support.

IC Role / Device Role / Timing Role: Low-noise, high-CMRR amplifier rejecting ignition noise while preserving signal fidelity. Use Value: 9 nV/√Hz noise floor maintains SNR > 80 dB at 1 kHz; 75 dB CMRR suppresses common-mode interference from adjacent power stages. |
Use Scenario: Driving analog gauges and backlight dimming control in digital instrument panels. IC Role / Device Role / Timing Role: Dual op amp providing buffered reference voltage and linear LED current regulation. Use Value: Dual-channel integration reduces board space vs discrete solutions; rail-to-rail output enables precise 0–3.3 V control of PWM dimming ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432-Q1 | Higher output drive (±50 mA), wider input voltage range (to VDD– + 0.1 V), but higher noise (25 nV/√Hz) | Better suited for driving heavy capacitive loads or low-impedance sensors; less optimal for ultra-low-noise sensor front-ends | Select TLV2432-Q1 when output current >20 mA or input common-mode extension beyond VDD– is required |
| LM7332-Q1 | Higher slew rate (10 V/μs), higher bandwidth (20 MHz), but higher supply current (2.3 mA/channel vs 3 mA total) | Preferred for high-speed control loops (e.g., EPS motor current sensing), not optimized for low-noise DC precision | Choose LM7332-Q1 for applications demanding >5 MHz bandwidth or sub-microsecond settling, where noise is secondary |
Compared with TLV2432-Q1 and LM7332-Q1, the TLC2272QPWRG4Q1 offers the lowest input voltage noise and tightest input offset voltage specification among AEC-Q100 dual op amps in its class - making it optimal for precision DC-coupled automotive sensing where signal integrity outweighs raw speed or drive strength.
