Product details
Overview
TLV2252AQDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output, automotive-qualified CMOS operational amplifier optimized for low-voltage, micropower operation. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 850 µV max input offset voltage (TA = 25°C), 34 µA per channel supply current, and operates from 2.7 V to 16 V. It is used in precision signal conditioning of high-impedance piezoelectric transducers within automotive cabin sensors.
For engineers reviewing the TLV2252AQDRQ1 datasheet, TLV2252AQDRQ1 pinout, TLV2252AQDRQ1 application, or TLV2252AQDRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to 125°C), rail-to-rail output swing, ultra-low input bias current (1 pA typ), and guaranteed 850 µV max VIO across temperature - critical for battery-powered automotive front-end analog stages interfacing with ADCs.
Technical Context
The TLV2252AQDRQ1 employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), low noise, and rail-to-rail output capability without external charge pumps. Its input stage supports common-mode voltage down to the negative rail (VDD−), enabling single-supply operation with ground-referenced inputs.
It features internal ESD protection exceeding 2000 V (MIL-STD-883, Method 3015) and 150 V (machine model), and is fully characterized over −40°C to 125°C with guaranteed performance at 3 V and 5 V supplies. The device includes macromodel support for SPICE simulation and is optimized for low-noise, low-drift small-signal amplification in safety-critical automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct integration into 3.3 V, 5 V, and 12 V automotive domains without level-shifting. |
| Input Offset Voltage (max) | 850 µV at TA = 25°C - ensures ≤0.085% gain error in 1 V full-scale sensor interfaces. |
| Supply Current (per channel) | 34 µA typical - supports >10-year battery life in always-on vehicle occupancy or door-handle sensors. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - four times lower than prior micropower CMOS op-amps, critical for piezo-acoustic signal fidelity. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs (e.g., 12-bit SAR) with no headroom loss at 3 V supply. |
| Common-Mode Input Range | Includes VDD− - allows true ground-referenced input in single-supply configurations (e.g., thermistor bridges). |
| ESD Rating | 2000 V HBM, 150 V MM - meets automotive module-level robustness requirements for under-hood and interior modules. |
Pinout & Package
TLV2252AQDRQ1 is housed in an 8-pin SOIC (D) package with standard pinout for dual op-amps. The package is RoHS-compliant, lead-free, and qualified for reflow per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|

| 2 | IN1− | Inverting input of Amp 1 - accepts differential or single-ended feedback networks. |
| 3 | IN1+ | Non-inverting input of Amp 1 - connects to high-Z sensor nodes (e.g., piezo element) with minimal loading. |
| 4 | GND / VDD− | Negative supply / ground reference - shared return path for both amplifiers and system ground plane. |
| 5 | VDD+ | Positive supply - accepts 2.7–16 V DC; decoupling capacitor required at pin for stability. |
| 6 | IN2+ | Non-inverting input of Amp 2 - enables dual-sensor monitoring (e.g., left/right seat occupancy). |
| 7 | IN2− | Inverting input of Amp 2 - supports independent gain configuration per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2252QDRQ1 | 1500 µV max VIO (vs. 850 µV for TLV2252AQDRQ1); otherwise identical specs and pinout. | Suitable for less demanding automotive signal chains where offset drift tolerance is relaxed. | Select TLV2252QDRQ1 only if system-level calibration compensates for higher initial offset. |
| OPA2333QDGKRQ1 | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift; higher supply current (17 µA/ch vs. 34 µA/ch). | Better for ultra-precision applications like battery voltage monitoring where long-term drift dominates error budget. | Choose OPA2333QDGKRQ1 when <1 µV offset stability over temperature and time outweighs micropower priority. |
Compared with TLV2252QDRQ1, TLV2252AQDRQ1 offers tighter offset specification for uncalibrated front-ends; compared with OPA2333QDGKRQ1, it trades zero-drift performance for half the supply current and simpler design-in in cost-sensitive automotive modules.

FAQ
What is the maximum operating temperature range for TLV2252AQDRQ1?
The TLV2252AQDRQ1 is AEC-Q100 Grade 1 qualified and specified for continuous operation from −40°C to +125°C ambient temperature. This rating is verified per automotive stress test standards and applies across the full 2.7 V to 16 V supply range. All electrical parameters in the datasheet - including input offset voltage, supply current, and output swing - are guaranteed across this range.
Does TLV2252AQDRQ1 support true rail-to-rail input?
No, TLV2252AQDRQ1 does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+ − 1.3 V) at 3 V supply, and similarly at higher voltages. However, the output is fully rail-to-rail, delivering 0 V to VDD swing into ≥10 kΩ loads - a key distinction confirmed in the "Recommended Operating Conditions" table of the SGLS192B datasheet.
Is TLV2252AQDRQ1 pin-compatible with TLV2252AQPWRQ1?
No, TLV2252AQDRQ1 (SOIC-8) and TLV2252AQPWRQ1 (TSSOP-8) share identical pin functions but differ in physical package and footprint. They are electrically and functionally equivalent, but PCB layout must be redesigned to accommodate the smaller TSSOP-8 body and finer pitch (0.65 mm vs. 1.27 mm). No pin mapping change is required - pin 1 (OUT1) through pin 8 (OUT2) retain identical roles.
What is the typical supply current per channel for TLV2252AQDRQ1 at 125°C?
At TA = 125°C and VDD = 3 V or 5 V, the TLV2252AQDRQ1 has a maximum supply current of 150 µA total (75 µA per channel). This value is explicitly specified in the "TLV2252-Q1 electrical characteristics" tables under "IDD Supply current" for full temperature range. Typical current remains near 34 µA per channel, but design margin must use the 75 µA/channel worst-case figure.
Can TLV2252AQDRQ1 drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, TLV2252AQDRQ1 guarantees rail-to-rail output swing into loads ≥10 kΩ, as confirmed by the "VOH High-level output voltage" and "VOL Low-level output voltage" specifications in the datasheet. At VDD = 3 V and IOH = −75 µA (equivalent to 3 V / 10 kΩ = 300 µA sink), VOH = 2.9 V and VOL = 0.1 V - confirming >96% of full rail span. Performance degrades below 10 kΩ due to output stage limitations.
