Product details
Overview
TLC2252QDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output, automotive-qualified operational amplifier optimized for ultra-low-power operation (35 µA per channel typ), low input bias current (1 pA typ), and low noise (19 nV/√Hz at 1 kHz). It operates from ±2.2 V to ±8 V supplies, supports common-mode input down to the negative rail, and delivers full rail-to-rail output swing - making it ideal for battery-powered sensor signal conditioning and ADC interfacing in harsh automotive environments.
For engineers reviewing the TLC2252QDRQ1 datasheet, TLC2252QDRQ1 pinout, TLC2252QDRQ1 application, or TLC2252QDRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to 125°C), 1550 µV max input offset voltage over temperature, SOIC-8 package, and compatibility with single- or split-supply systems requiring micropower precision amplification.
Technical Context
The TLC2252QDRQ1 uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), rail-to-rail output swing, and stable unity-gain operation with 63° phase margin. Its input stage includes ESD protection exceeding 2000 V (HBM) and 150 V (machine model), and it features fully characterized performance across −40°C to 125°C.
It is specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) operation, with common-mode input range extending to VDD− and output swing within 100 mV of both rails under 500 µA load. The device exhibits 0.2 MHz gain-bandwidth product and 0.07 V/µs slew rate at unity gain with 100 kΩ load.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2252AQDRQ1 | Lower max input offset voltage (850 µV vs. 1550 µV) over temperature; otherwise identical specs and pinout | Better suited for higher-precision applications like battery cell voltage monitoring where offset drift impacts accuracy | Select TLC2252AQDRQ1 when <1 mV total offset error budget is required; same PCB layout and qualification status |
| TLV2432IDR | Higher supply current (125 µA/ch), wider GBW (2.8 MHz), but not AEC-Q100 qualified; SOIC-8 package | Targeted at industrial/commercial systems needing faster response, not automotive safety-critical functions | Choose TLV2432IDR only for non-automotive designs; lacks automotive qualification and has 3.6× higher quiescent current |
