Product details
Overview
TLC2274AQDRG4Q1 from Texas Instruments is a quad, rail-to-rail output, LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), with 2.2 MHz gain-bandwidth product, 3.6 V/μs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz. It delivers low input bias current (1 pA typical), low input offset voltage (≤950 μV max at 25°C), and full rail-to-rail output swing - enabling high-precision signal conditioning in automotive body control modules and battery management systems.
For engineers reviewing the TLC2274AQDRG4Q1 datasheet, TLC2274AQDRG4Q1 pinout, TLC2274AQDRG4Q1 application, or TLC2274AQDRG4Q1 equivalent, key selection criteria include its automotive-grade temperature range, rail-to-rail output capability under single- or split-supply operation, low-noise performance for high-impedance sensor interfaces, and functional safety documentation support.
Technical Context
The TLC2274AQDRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for precision analog signal conditioning in harsh automotive environments. Its input stage features ultra-low input bias current (1 pA typ) and common-mode input range extending to the negative rail, while the output stage supports full swing from VDD− to VDD+ across load currents up to ±1 mA.
It operates over ±2.2 V to ±8 V dual supply or 4.4 V to 16 V single supply, with guaranteed performance across –40°C to 125°C. The device includes internal ESD protection per AEC-Q100 (HBM ±2000 V, CDM ±1000 V) and supports functional safety system design via TI's documented safety analysis package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434-Q1 | Higher supply current (1.2 mA/ch vs 1.5 mA total for TLC2274AQDRG4Q1), lower GBW (1.8 MHz), no AEC-Q100 Grade 1 rating | Targeted at cost-sensitive non-safety-critical modules; lacks functional safety documentation | Choose TLV2434-Q1 only if lower power is not required and ASIL-B compliance is unnecessary |
| LMV844QDGRTQ1 | Lower input offset voltage (350 μV max), higher quiescent current (1.25 mA/ch), rail-to-rail input/output, but only 1.2 MHz GBW | Better DC accuracy for ultra-precision sensor front-ends; less suitable for higher-frequency feedback loops | Select LMV844QDGRTQ1 when sub-500 μV offset is mandatory and bandwidth ≤1 MHz suffices |
Compared with TLV2434-Q1 and LMV844QDGRTQ1, the TLC2274AQDRG4Q1 uniquely balances AEC-Q100 Grade 1 qualification, functional safety support, 2.25 MHz bandwidth, and ultra-low input bias current - making it optimal for integrated automotive signal chains requiring both precision and robustness.
