Product details
Overview
TLC2264AQPWRG4Q1 from Texas Instruments is a quad rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C), featuring 950 µV max input offset voltage, 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, and 500 µA per amplifier supply current. It enables high-precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2264AQPWRG4Q1 datasheet, TLC2264AQPWRG4Q1 pinout, TLC2264AQPWRG4Q1 application, or TLC2264AQPWRG4Q1 equivalent, key selection criteria include its A-grade precision (950 µV VIO), rail-to-rail output swing, low-noise CMOS architecture, and TSSOP-14 automotive qualification - critical for analog front-end design in harsh-environment vehicle systems.
Technical Context
The TLC2264AQPWRG4Q1 implements a CMOS-input, rail-to-rail output op-amp topology with fully differential input stage and Class AB output buffer. Its input stage delivers ultra-low bias current (1 pA typ) and high common-mode rejection (83 dB min), while the output stage supports full swing from VDD−/GND to VDD+ across ±2.2 V to ±8 V supplies.
It operates over dual-supply (±2.2 V to ±8 V) or single-supply (4.4 V to 16 V) configurations, with guaranteed performance across −40°C to 125°C. Input common-mode range extends to the negative rail, and output swing includes both rails - enabling direct interfacing with 5 V or 3.3 V ADCs without level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434QDRQ1 | Higher supply current (1.25 mA), lower VIO (700 µV), no rail-to-rail input | Better DC precision but reduced input common-mode range - unsuitable for single-supply sensor biasing | Select when ultra-low offset dominates over input voltage range and power |
| LMV324QDRQ1 | Lower cost, higher VIO (3 mV), higher noise (25 nV/√Hz), not AEC-Q100 qualified | Acceptable for non-safety-critical cabin controls but fails ASIL requirements for powertrain use | Select only for cost-sensitive, non-automotive industrial applications |
Compared with TLV2434QDRQ1 and LMV324QDRQ1, the TLC2264AQPWRG4Q1 uniquely balances AEC-Q100 qualification, rail-to-rail output, 950 µV VIO, and 1 pA IIB - making it the only option meeting full ASIL-B analog front-end requirements without trade-offs in noise, power, or input range.

FAQ
What is the maximum operating temperature range for the TLC2264AQPWRG4Q1?
The TLC2264AQPWRG4Q1 is rated for −40°C to 125°C ambient operating temperature, fully qualified to AEC-Q100 Grade 1 standards. This range is validated across all electrical parameters including input offset voltage, CMRR, and supply current - ensuring reliable operation in under-hood and transmission-control environments where thermal stress is extreme.
Does the TLC2264AQPWRG4Q1 support single-supply operation?
Yes, the TLC2264AQPWRG4Q1 supports true single-supply operation from 4.4 V to 16 V. Its input common-mode range includes the negative rail (VDD−/GND), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interface with 5 V or 3.3 V ADCs without level-shifting circuitry or dual supplies.
What is the input offset voltage specification for the TLC2264AQPWRG4Q1?
The TLC2264AQPWRG4Q1 has a maximum input offset voltage of 950 µV at 25°C and 1500 µV over the full −40°C to 125°C temperature range. This A-grade precision is guaranteed per device and enables high-accuracy amplification in closed-loop transducer systems such as pressure and temperature sensing.
How does the noise performance of the TLC2264AQPWRG4Q1 compare to legacy automotive op-amps?
The TLC2264AQPWRG4Q1 delivers 12 nV/√Hz input voltage noise at 1 kHz - a 50% improvement over earlier TLC27M4 and TS27M4 automotive op-amps. Combined with 0.6 fA/√Hz current noise, this enables clean amplification of microvolt-level signals from piezoresistive or capacitive sensors without degrading system SNR.
Is the TLC2264AQPWRG4Q1 pin-compatible with the standard TLC2264QPWRQ1?
Yes, the TLC2264AQPWRG4Q1 is pin-compatible with the TLC2264QPWRQ1 and all other TLC2264 variants in TSSOP-14 packaging. Both share identical pinout, footprint, and thermal characteristics - allowing drop-in replacement where tighter input offset voltage (950 µV vs. 2.5 mV) and lower drift are required.
