Product details
Overview
TLV2252QDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output, micropower operational amplifier qualified for automotive applications (AEC-Q100 Grade 1, −40°C to +125°C). It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 34 µA per channel supply current across 2.7 V to 16 V supply range - enabling high-precision signal conditioning in battery-powered vehicle subsystems such as cabin sensor interfaces and body control modules.
For engineers reviewing the TLV2252QDRQ1 datasheet, TLV2252QDRQ1 pinout, TLV2252QDRQ1 application, or TLV2252QDRQ1 equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, automotive-grade reliability context, and validated alternative options for low-noise, low-power op-amp selection in safety-critical analog front-ends.
Technical Context
The TLV2252QDRQ1 employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low input offset voltage (1500 µV max over full temperature range). Its common-mode input voltage range extends to the negative rail, supporting single-supply operation down to 2.7 V with full dynamic range utilization.
Designed for precision analog signal chains, it features 65 dB minimum CMRR and 80 dB minimum PSRR across −40°C to +125°C, with stable unity-gain operation into 100 pF capacitive loads and 63° phase margin - making it suitable for driving ADC inputs and high-impedance transducer buffers without external compensation.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct connection to automotive 3.3 V, 5 V, and 12 V rails without regulation. |
| Input Bias Current | 1 pA typical - enables accurate amplification of signals from high-impedance sources like piezoelectric sensors. |
| Input Offset Voltage | 1500 µV maximum over −40°C to +125°C - ensures minimal DC error in closed-loop configurations. |
| Output Swing | Rail-to-rail - delivers full-scale analog output into ADCs with no headroom loss at low supply voltages. |
| Supply Current per Channel | 68 µA typical at 25°C (136 µA total) - enables multi-channel sensing in always-on automotive modules. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - reduces integrated noise in bandwidth-limited sensor interfaces below 10 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2252AQDRQ1 | 850 µV max input offset voltage (vs. 1500 µV for TLV2252QDRQ1); otherwise identical specs and pinout. | Required where DC accuracy exceeds ±1 mV in 3.3 V systems (e.g., precision current sensing). | Select TLV2252AQDRQ1 when VIO budget is constrained; same PCB layout and thermal profile. |
| LMV721QDRQ1 | Higher supply current (120 µA/ch), wider GBW (1.5 MHz), but only 70 dB CMRR and no rail-to-rail input. | Suitable for higher-speed signal paths (>100 kHz) where offset and noise are secondary to bandwidth. | Choose LMV721QDRQ1 for mixed-signal timing-critical nodes; verify input common-mode compliance. |
Compared with TLV2252AQDRQ1, TLV2252QDRQ1 trades 650 µV higher VIO for lower cost in volume automotive production; versus LMV721QDRQ1, it delivers superior DC precision and rail-to-rail output at the expense of bandwidth - critical for sensor front-ends where accuracy outweighs speed.

FAQ
What is the operating temperature range for TLV2252QDRQ1?
The TLV2252QDRQ1 is qualified for automotive Grade 1 operation, with a guaranteed functional temperature range of −40°C to +125°C. All electrical specifications - including input offset voltage, supply current, and CMRR - are tested and specified across this full range, making TLV2252QDRQ1 suitable for under-hood and chassis-mounted applications where ambient temperatures exceed 105°C.
Does TLV2252QDRQ1 support true rail-to-rail input?
No, TLV2252QDRQ1 features rail-to-rail output only. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+) at 3 V supply, and 2.7 V below VDD+ at 5 V supply. This design prioritizes low input bias current and noise over full rail-to-rail input - confirmed in the "Recommended Operating Conditions" table of the datasheet.
Can TLV2252QDRQ1 drive a 10 kΩ load at 3.3 V supply?
Yes, TLV2252QDRQ1 can drive a 10 kΩ load at 3.3 V supply while maintaining rail-to-rail output swing. At VOH = 3.28 V and VOL = 0.02 V (typical, IOH/IOL = ±50 µA), the output stage delivers full dynamic range into 10 kΩ. The datasheet confirms stable operation up to ±50 mA short-circuit current, far exceeding requirements for typical sensor interface loads.
How does TLV2252QDRQ1 compare to TLV2322 in automotive designs?
TLV2252QDRQ1 replaces TLV2322 in automotive applications by offering 4× lower input voltage noise (19 nV/√Hz vs. 75 nV/√Hz), 1500 µV max VIO (vs. 3000 µV), and enhanced ESD robustness (2000 V HBM). Both are dual op-amps in SOIC-8, but TLV2252QDRQ1's AEC-Q100 qualification, wider supply range (2.7–16 V), and rail-to-rail output make it the preferred upgrade for new automotive designs requiring improved signal fidelity.
Is a bypass capacitor required for TLV2252QDRQ1 stability?
Yes, a 0.1 µF ceramic bypass capacitor is required between VDD+ (Pin 5) and GND (Pin 4), placed within 2 mm of the device. This minimizes supply impedance at high frequencies and prevents oscillation due to parasitic inductance - explicitly mandated in the "Layout Guidelines" section of the TLV2252-Q1 datasheet to ensure 63° phase margin and stable unity-gain operation.
