Product details
Overview
TLC2252QDREP from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for micropower, low-noise precision signal conditioning in extended-temperature industrial and automotive applications. It delivers 19 nV/√Hz input-referred noise at 1 kHz, 1 pA typical input bias current, 35 µA per channel supply current, and rail-to-rail output swing from ±2.2 V to ±8 V supplies - enabling high-fidelity sensor interfacing in battery-powered remote monitoring systems.
For engineers reviewing the TLC2252QDREP datasheet, TLC2252QDREP pinout, TLC2252QDREP application, or TLC2252QDREP equivalent, key selection criteria include its −40°C to 125°C qualified operation, 850 µV max input offset voltage (TLC2252A-grade), common-mode input range extending to the negative rail, and SOIC-8 package compatibility with legacy CMOS op-amp footprints.
Technical Context
The TLC2252QDREP employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) while maintaining rail-to-rail output capability across full supply range (±2.2 V to ±8 V). Its input stage supports common-mode voltages down to VDD−, making it suitable for single-supply transducer amplification without level-shifting circuitry.
Internally compensated for unity-gain stability with 63° phase margin and 15 dB gain margin into 50 kΩ//100 pF loads, the device features a 0.2 MHz gain-bandwidth product and 0.07 V/µs slew rate - balancing bandwidth, power, and precision for DC-coupled, low-frequency measurement paths.
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 |
|---|---|---|---|
| TLC2252AQDREP | 850 µV max input offset voltage (vs. 1550 µV for TLC2252QDREP); same package, pinout, and temperature range. | Suitable for higher-precision DC measurements where offset drift must be minimized. | Select when system-level offset budget requires tighter initial VIO specification without changing layout or firmware. |
| TLV2432IDR | Higher 1.2 mA supply current per channel; 0.5 V/µs slew rate; 2.7–6 V supply only; no extended-temp qualification. | Better AC performance but unsuitable for extended-temperature or ultra-low-power designs. | Choose only for cost-sensitive consumer applications within 0°C to 70°C ambient, where power and temperature margins are relaxed. |
Compared with TLC2252AQDREP, the TLC2252QDREP trades initial offset accuracy for broader availability and lower cost in high-volume automotive/industrial programs; versus TLV2432IDR, it delivers 17× lower quiescent current and guaranteed operation to 125°C - critical for uncooled embedded deployments.

FAQ
What is the maximum operating temperature range for the TLC2252QDREP?
The TLC2252QDREP is fully specified and qualified for continuous operation from −40°C to 125°C. This extended temperature range is validated per JEDEC standards including HAST, temperature cycling, and electromigration testing - making it suitable for under-hood automotive and industrial control applications where ambient temperatures exceed standard commercial grade limits.
Does the TLC2252QDREP support single-supply operation?
Yes, the TLC2252QDREP supports true single-supply operation from 4.4 V to 16 V. Its input common-mode range extends to the negative rail (VDD−), and its rail-to-rail output can swing within 10 mV of either supply rail under light load - enabling direct interfacing with 0–5 V ADCs and microcontroller analog inputs without external biasing networks.
What is the input offset voltage specification for TLC2252QDREP over temperature?
The TLC2252QDREP has a maximum input offset voltage of 1550 µV across the full −40°C to 125°C operating range. At 25°C, the typical value is 200 µV with a maximum of 1500 µV. Its temperature coefficient is 0.5 µV/°C, meaning offset drift contributes less than 50 µV over a 100°C span - critical for stable DC gain accuracy in closed-loop systems.
Can TLC2252QDREP drive capacitive loads directly?
The TLC2252QDREP is internally compensated for unity-gain stability with 63° phase margin into 50 kΩ//100 pF loads. Driving larger capacitive loads (>100 pF) may cause peaking or oscillation; for such cases, an isolation resistor (e.g., 10–100 Ω) between the output and load capacitance is recommended to maintain stability without degrading bandwidth significantly.
How does TLC2252QDREP compare to TLC2252AQDREP in terms of precision?
The TLC2252QDREP and TLC2252AQDREP share identical packaging, pinout, and temperature rating, but differ in input offset voltage: TLC2252QDREP is specified at 1550 µV max over temperature, while TLC2252AQDREP is binned to 850 µV max. Both offer the same 1 pA input bias current and 19 nV/√Hz noise - so the choice depends strictly on whether the application's DC accuracy budget permits the higher offset tolerance.
