Product details
Overview
TLC2274AQPWRQ1 from Texas Instruments is a quad, rail-to-rail output, precision operational amplifier qualified for automotive applications (AEC-Q100 Grade 1, –40°C to 125°C). It delivers 2.2 MHz gain-bandwidth, 3.6 V/μs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and ≤950 μV maximum input offset voltage at 25°C - enabling high-fidelity signal conditioning in battery management and engine control systems.
For engineers reviewing the TLC2274AQPWRQ1 datasheet, TLC2274AQPWRQ1 pinout, TLC2274AQPWRQ1 application, or TLC2274AQPWRQ1 equivalent, key selection criteria include rail-to-rail output swing with ±2.2 V to ±8 V supply operation, low-noise performance for piezoelectric sensor interfaces, and functional safety documentation support for ISO 26262-compliant designs.
Technical Context
The TLC2274AQPWRQ1 uses LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), low input bias current (1 pA typ), and rail-to-rail output swing - critical for interfacing with SAR ADCs in single-supply automotive subsystems. Its common-mode input range extends to the negative rail, supporting ground-referenced sensor inputs.
It operates across dual-supply (±2.2 V to ±8 V) and single-supply (4.4 V to 16 V) configurations, with specified performance over –40°C to 125°C. The device exhibits 75 dB typical CMRR and 95 dB typical PSRR, ensuring robust operation in noisy vehicle electrical environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434AQPWRQ1 | Higher slew rate (1.5 V/μs), lower quiescent current (125 μA/ch), but only 550 kHz GBW and no AEC-Q100 Grade 1 rating. | Targeted at ultra-low-power body electronics; insufficient bandwidth for EPS motor current loop closure. | Select when power budget is primary constraint and bandwidth <600 kHz suffices. |
| LM2902QDRQ1 | Lower cost, wider supply range (3–32 V), but higher input offset (±3 mV), no rail-to-rail output, and 1.2 MHz GBW. | Used in non-critical HVAC and lighting controls where precision and dynamic range are secondary. | Select for cost-sensitive applications where 950 μV offset and rail-to-rail swing are not required. |
Compared with TLV2434AQPWRQ1 and LM2902QDRQ1, TLC2274AQPWRQ1 provides superior AC performance (2.25 MHz GBW, 3.6 V/μs), guaranteed automotive-grade precision (≤950 μV VIO), and rail-to-rail output - making it optimal for safety-critical, high-fidelity analog signal paths in modern E/E architectures.

FAQ
What is the maximum supply voltage for TLC2274AQPWRQ1 in dual-supply operation?
The TLC2274AQPWRQ1 supports dual-supply operation from ±2.2 V to ±8 V. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ –8 V, with differential supply voltage not exceeding 16 V. Operation beyond ±8 V risks permanent damage per Section 6.1 of the datasheet. For reliable long-term use in automotive environments, TI recommends staying within the recommended operating conditions of ±2.2 V to ±8 V.
Does TLC2274AQPWRQ1 support single-supply operation with 5 V?
Yes, TLC2274AQPWRQ1 is fully specified for single-supply operation from 4.4 V to 16 V. At VDD = 5 V, it delivers rail-to-rail output swing, 2.18 MHz gain-bandwidth, and ≤950 μV input offset voltage - making it ideal for 5 V microcontroller-based automotive modules such as instrument clusters and telematics control units.
Is TLC2274AQPWRQ1 pin-compatible with standard TLC2274 variants?
No - TLC2274AQPWRQ1 uses the same 14-pin TSSOP (PW) footprint as non-automotive TLC2274 variants, but its internal specifications (AEC-Q100 Grade 1 qualification, functional safety documentation, and tighter VIO limits) are unique to the Q1 suffix. Electrical behavior matches the TLC2274A-Q1 family, not generic TLC2274.
What thermal derating applies to TLC2274AQPWRQ1 in a 14-pin TSSOP package?
In its 14-pin TSSOP (PW) package, TLC2274AQPWRQ1 has RθJA = 111.6°C/W. At 125°C ambient and 6 mA total supply current (4.8 mA typical), power dissipation is ~30 mW, resulting in ~3.4°C junction rise - well within safe limits. No external heatsinking is required for standard automotive mounting conditions.
Where can I find the SPICE macromodel for TLC2274AQPWRQ1?
The verified SPICE macromodel for TLC2274AQPWRQ1 is available on the Texas Instruments product folder page for TLC2274A-Q1 (https://www.ti.com/product/TLC2274A-Q1) under "Design & development" → "Simulation model". It supports transient, AC, and DC analyses in PSpice and TINA-TI environments.
