Product details
Overview
TLC2252AQPWRQ1 from Texas Instruments is a dual-channel, rail-to-rail output, automotive-qualified operational amplifier featuring 850 µV max input offset voltage at 25°C, 19 nV/√Hz input noise at 1 kHz, and 35 µA per channel supply current. 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-ideal for precision signal conditioning in battery-powered automotive sensor interfaces.
For engineers reviewing the TLC2252AQPWRQ1 datasheet, TLC2252AQPWRQ1 pinout, TLC2252AQPWRQ1 application, or TLC2252AQPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to 125°C), ultra-low input bias current (1 pA typ), low-noise micropower operation, and compatibility with single- or split-supply ADC front-ends in safety-critical vehicle subsystems.
Technical Context
The TLC2252AQPWRQ1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>10¹² Ω) and low input bias current. Its internal architecture includes ESD-protected input stages (exceeding 150 V MM) and a fully differential output stage optimized for stability with capacitive loads up to 100 pF.
It is characterized across −40°C to 125°C with guaranteed parameters including 70 dB min CMRR, 80 dB min PSRR, 0.07 V/µs min slew rate, and 0.2 MHz gain-bandwidth product-enabling stable unity-gain buffer and low-frequency transducer amplification without phase margin degradation.
Key Specifications

Pinout & Package
TLC2252AQPWRQ1 is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). The package is RoHS-compliant and qualified per AEC-Q100 Grade 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives low-impedance loads up to ±50 mA; rail-to-rail swing ensures full ADC utilization |
| 2 | IN1− | Inverting input - high-impedance node (10¹² Ω) minimizes loading on high-Z sources like pH electrodes |
| 3 | IN1+ | Non-inverting input - accepts common-mode voltages down to VDD−, enabling single-supply sensor biasing |
| 4 | VDD− / GND | Negative supply or ground reference - shared return path for both amplifiers; decoupling required near pin |
| 5 | VDD+ | Positive supply - accepts up to +8 V; internal regulation not present; external filtering essential |
| 6 | IN2+ | Non-inverting input (amp 2) - independently configurable; no crosstalk specified between channels |
| 7 | IN2− | Inverting input (amp 2) - matched offset and bias performance to channel 1 per datasheet characterization |
| 8 | OUT2 | Amplifier 2 output - identical AC/DC specs to OUT1; supports dual-sensor or differential pair implementation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers >99% of supply rails at 100 µA load - eliminates need for external level shifters in 3.3 V or 5 V ADC interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher supply current (600 µA/ch), wider GBW (2.2 MHz), but no AEC-Q100 qualification | Suitable for non-automotive industrial control where speed outweighs power constraints | Select when >1 MHz bandwidth is required and automotive qualification is unnecessary |
| LM7332MA/NOPB | Higher drive capability (±75 mA), higher noise (29 nV/√Hz), AEC-Q100 Grade 1, but 1.1 mA/ch supply current | Better for driving heavy capacitive loads or low-impedance cables in ADAS camera modules | Select when output current >50 mA or faster settling is critical, accepting 30× higher quiescent power |
Compared with TLV2432IDR and LM7332MA/NOPB, the TLC2252AQPWRQ1 uniquely balances automotive qualification, micropower operation (<35 µA/ch), and precision (850 µV VIO) - making it optimal for always-on, thermally constrained vehicle subsystems where power and drift are primary constraints.

FAQ
What is the maximum operating temperature range for the TLC2252AQPWRQ1?
The TLC2252AQPWRQ1 is qualified per AEC-Q100 Grade 1 and operates from −40°C to +125°C ambient temperature. All electrical specifications-including input offset voltage, supply current, and CMRR-are guaranteed across this full range, with test data provided in the datasheet for −40°C, 25°C, and 125°C conditions. This makes the TLC2252AQPWRQ1 suitable for under-hood and transmission-control applications.
Does the TLC2252AQPWRQ1 support single-supply operation?
Yes, the TLC2252AQPWRQ1 is fully specified for single-supply operation from 4.4 V to 16 V (VDD+ to GND), with rail-to-rail output swing and common-mode input range extending to the negative rail (GND). Input common-mode range is 0 V to VDD+ − 1.5 V at 25°C, and output can swing within 10 mV of both rails at light loads-enabling direct interface with 3.3 V or 5 V microcontroller ADCs without level-shifting circuitry.
What is the input offset voltage specification for the TLC2252AQPWRQ1?
The TLC2252AQPWRQ1 has a maximum input offset voltage of 850 µV at TA = 25°C and 1000 µV over the full −40°C to +125°C operating range. This is the "A" grade variant-distinct from the standard TLC2252QDRQ1 (1550 µV max at 25°C). The low VIO enables high-accuracy DC amplification in closed-loop sensor systems such as throttle position or brake pressure transducers.
Is the TLC2252AQPWRQ1 pin-compatible with older TI op-amps like the TLC27L2?
No, the TLC2252AQPWRQ1 is not pin-compatible with the TLC27L2. While both are dual op-amps in 8-pin SOIC or TSSOP packages, the pin assignments differ: TLC2252AQPWRQ1 uses pin 4 as VDD−/GND and pin 5 as VDD+, whereas TLC27L2 uses pin 4 as VDD− and pin 8 as VDD+. Additionally, TLC2252AQPWRQ1 offers rail-to-rail output and lower VIO-requiring PCB layout revision for drop-in replacement, though it serves as a functional upgrade in most sensor signal chains.
What packaging and marking information applies to the TLC2252AQPWRQ1?
The TLC2252AQPWRQ1 is supplied in an 8-pin TSSOP (PW) package with tape-and-reel packaging. Top-side marking is "2252AQ", consistent across all TLC2252A-Q1 variants in PW packaging. The device features a moisture sensitivity level (MSL) of 2a per J-STD-020, and the package drawing conforms to TI's PW00008B standard with 0.65 mm lead pitch and 3.0 mm × 4.4 mm body dimensions.
