Product details
Overview
TLC2252QPWRQ1 from Texas Instruments is a dual, rail-to-rail output, automotive-qualified operational amplifier featuring 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV maximum input offset voltage at 25°C. 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 low-power sensor signal conditioning in battery-powered automotive ECUs.
For engineers reviewing the TLC2252QPWRQ1 datasheet, TLC2252QPWRQ1 pinout, TLC2252QPWRQ1 application, or TLC2252QPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, micropower consumption, rail-to-rail output capability, low-input-bias-current (1 pA typ), and compatibility with single- or split-supply ADC interface circuits.
Technical Context
The TLC2252QPWRQ1 implements an Advanced LinCMOS™ process architecture optimized for ultra-low power and high input impedance. Its input stage uses complementary MOSFET pairs enabling rail-to-rail common-mode input range including the negative supply rail and sub-picoampere input bias current.
Output stage employs push-pull CMOS topology delivering true rail-to-rail swing under load, with 0.07–0.12 V/µs slew rate and 0.2 MHz gain-bandwidth product. It is fully characterized across −40°C to +125°C and specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 70–125 µA per channel at 25°C - enables multi-year battery life in always-on vehicle sensors. |
| Input Offset Voltage | ≤850 µV max at 25°C (TLC2252A-Q1 variant) - ensures <0.1% DC error in precision bridge amplification. |
| Input Bias Current | 1 pA typical - preserves signal integrity when interfacing high-impedance sources like piezoelectric transducers. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - 4× lower than legacy micropower CMOS op-amps, critical for low-level analog front-ends. |
| Rail-to-Rail Output | Swing includes both supply rails (e.g., 0 V to 5 V on 5 V supply) - maximizes dynamic range into SAR or delta-sigma ADCs. |
| Common-Mode Input Range | Extends to VDD− (negative rail) - allows direct sensing of ground-referenced signals without level-shifting circuitry. |
| ESD Protection | ≥150 V (machine model) - meets automotive board handling requirements per AEC-Q100 stress test guidelines. |
Pinout & Package
TLC2252QPWRQ1 is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm body, and exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing supports full ADC input range utilization. |
| 2 | IN1− | Inverting input of Amp1 - high-impedance node (10¹² Ω) minimizes loading on passive filter networks. |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts common-mode voltages from VDD− to VDD+ −1.5 V. |
| 4 | VDD− / GND | Negative supply or ground reference - serves as return path for both amplifiers and enables single-supply operation. |
| 5 | VDD+ | Positive supply - accepts 2.2 V to 8 V (single) or ±2.2 V to ±8 V (split); internal regulation not required. |
| 6 | IN2− | Inverting input of Amp2 - electrically isolated from Amp1; supports dual-channel independent signal paths. |
| 7 | IN2+ | Non-inverting input of Amp2 - identical electrical characteristics to Pin 3; enables matched dual-sensor conditioning. |
| 8 | OUT2 | Amplifier 2 output - independently configurable; no crosstalk observed in typical automotive EMC environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0 V to VDD range on 5 V supply - eliminates need for external level-shifting before 12-bit+ ADCs. |
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C) - qualified for engine control, body electronics, and ADAS sensor nodes. |
| Ultra-low input bias current | 1 pA typical - prevents signal degradation in high-Z pH, thermopile, or capacitive sensor interfaces. |
| Low-noise performance | 19 nV/√Hz at 1 kHz - enables accurate amplification of microvolt-level signals from strain gauges or current shunts. |
| Single- and split-supply support | Fully specified at 5 V and ±5 V - simplifies design reuse across 12 V battery systems and isolated subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, rail-to-rail, automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDRQ1 | Higher output drive (±30 mA vs ±50 mA), wider input voltage range (VDD− −0.3 V to VDD+ +0.3 V), but 125 µA/channel supply current. | Better suited for driving heavier capacitive loads or higher-current transducers; less optimal for ultra-low-power wake-up circuits. | Select TLV2432QDRQ1 when output short-circuit robustness or extended input range outweighs micropower priority. |
| LM7332QMA/NOPB | Higher slew rate (10 V/µs), wider GBW (21 MHz), but 2.3 mA/channel supply current and no rail-to-rail input. | Targeted at high-speed active filters or PWM feedback loops - not suitable for battery-constrained sensor nodes. | Choose LM7332QMA/NOPB only for time-critical control loops where speed dominates power budget constraints. |
Compared with TLV2432QDRQ1 and LM7332QMA/NOPB, TLC2252QPWRQ1 uniquely balances AEC-Q100 qualification, rail-to-rail output, sub-100 µA/channel consumption, and pA-level input bias - making it the optimal choice for always-on, low-power automotive sensor interfaces where accuracy and longevity are paramount.

FAQ
What is the operating temperature range for the TLC2252QPWRQ1?
The TLC2252QPWRQ1 is qualified for automotive use with an operating free-air temperature range of −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements. All electrical specifications - including input offset voltage, supply current, and output swing - are guaranteed across this full range, ensuring consistent performance in under-hood and cabin-mounted applications.
Does the TLC2252QPWRQ1 support single-supply operation?
Yes, the TLC2252QPWRQ1 is fully specified for single-supply operation from 4.4 V to 16 V (VDD+ to GND). Its rail-to-rail output and common-mode input range extending to VDD− allow direct interfacing with 5 V or 12 V systems without level-shifting circuitry - a key advantage in modern automotive domain controllers.
How does the input offset voltage of TLC2252QPWRQ1 compare to the TLC2252QDRQ1?
The TLC2252QPWRQ1 belongs to the TLC2252A-Q1 variant, with a maximum input offset voltage of 850 µV at 25°C. In contrast, the TLC2252QDRQ1 (non-A version) has a maximum VIO of 1550 µV at 25°C. Both share identical pinout, package, and temperature range, but the 'A' suffix denotes tighter DC precision for applications demanding higher initial accuracy.
Can TLC2252QPWRQ1 drive capacitive loads directly?
The TLC2252QPWRQ1 is stable with capacitive loads up to 100 pF when configured as a unity-gain follower (phase margin = 63°). For larger loads (e.g., >200 pF), external isolation resistance (e.g., 100 Ω in series with output) is recommended to maintain stability - confirmed by Figure 39 in the datasheet showing slew rate vs. load capacitance.
Is there a SPICE macromodel available for TLC2252QPWRQ1?
Yes, a validated PSpice macromodel for the TLC2252QPWRQ1 is provided by Texas Instruments and included in the official product folder. The model accurately reproduces key behaviors including rail-to-rail output swing, input bias current, noise spectral density, and phase margin - enabling reliable pre-layout simulation of sensor front-end circuits before prototyping.
