Product details
Overview
TLC2252AQDRG4 from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier designed for precision signal conditioning in battery-powered and automotive systems. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and rail-to-rail output swing from ±2.2 V to ±8 V supplies. It is used in high-impedance sensor interfaces such as piezoelectric transducers and ADC front-ends.
For engineers reviewing the TLC2252AQDRG4 datasheet, TLC2252AQDRG4 pinout, TLC2252AQDRG4 application, or TLC2252AQDRG4 equivalent, this page provides verified electrical specifications, automotive-grade temperature range (–40°C to +125°C), Q-temp qualification status, package mapping to SOIC-8, and validated alternative options for low-power precision amplification.
Technical Context
The TLC2252AQDRG4 employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low power consumption. Its input stage includes common-mode input voltage range extending to the negative rail and supports both single-supply (e.g., 5 V) and split-supply (±5 V) operation.
It features fully characterized performance across –40°C to +125°C, with maximum input offset voltage of 850 µV (TLC2252A grade), 70 dB minimum CMRR, and 80 dB minimum PSRR - all specified under automotive operating conditions per AEC-Q100 guidelines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher drive capability (60 mA), wider input voltage range (to V– – 0.3 V), but higher supply current (600 µA/channel). | Better suited for driving heavier loads or rail-sensing circuits where output current >50 mA is required. | Select TLV2432IDR only if output drive or extended input range outweighs 17× higher quiescent current. |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, lower noise (1.1 µVPP, 0.1–10 Hz), but higher supply current (17 µA/channel). | Ideal for DC-critical applications like weigh scales or precision thermopile amplification where long-term offset stability dominates. | Choose OPA2333AIDR when µV-level offset drift over temperature is more critical than micropower operation. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2252AQDRG4 uniquely balances ultra-low power (35 µA), rail-to-rail output, and automotive qualification - making it optimal for cost-sensitive, battery-constrained, and thermally demanding signal chains where moderate DC precision suffices.

FAQ
What is the maximum supply voltage rating for the TLC2252AQDRG4?
The TLC2252AQDRG4 has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD– terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full electrical specifications guaranteed across that span at temperatures from –40°C to +125°C.
Does the TLC2252AQDRG4 support single-supply operation?
Yes, the TLC2252AQDRG4 fully supports single-supply operation from 4.4 V to 16 V. Its common-mode input voltage range includes the negative rail (GND), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interfacing with 3.3 V or 5 V ADCs without level-shifting circuitry.
Is the TLC2252AQDRG4 qualified for automotive applications?
Yes, the TLC2252AQDRG4 is Q-temp automotive qualified and meets AEC-Q100 Grade 2 requirements. It is rated for continuous operation from –40°C to +125°C ambient temperature and undergoes rigorous stress testing for reliability in under-hood and cabin-mounted automotive electronics.
What is the input offset voltage specification for the TLC2252AQDRG4?
The TLC2252AQDRG4 ('A' grade) specifies a maximum input offset voltage of 850 µV at TA = 25°C, with a full-range maximum of 1000 µV across –40°C to +125°C. This value is guaranteed and tested per production lot, supporting precision applications where trimming is impractical.
Can the TLC2252AQDRG4 drive capacitive loads directly?
The TLC2252AQDRG4 is stable with capacitive loads up to 100 pF when configured with unity-gain feedback and a 50 kΩ load resistor, as confirmed by phase margin (63°) and gain margin (15 dB) data. For larger capacitive loads (>100 pF), external isolation resistance or gain adjustment is recommended to maintain stability.
