Product details
Overview
TLV2252AQDRG4Q1 from Texas Instruments is a dual, rail-to-rail output, micropower operational amplifier qualified for automotive applications (AEC-Q100 Grade 1). It delivers 19 nV/√Hz input voltage noise at 1 kHz, 850 µV max input offset voltage at 25°C, and 34 µA per channel supply current across 2.7 V to 16 V operation - enabling precision signal conditioning in battery-powered vehicle sensors and low-voltage ADC interfaces.
For engineers reviewing the TLV2252AQDRG4Q1 datasheet, TLV2252AQDRG4Q1 pinout, TLV2252AQDRG4Q1 application, or TLV2252AQDRG4Q1 equivalent, this page provides verified technical context, automotive-grade specifications, SOIC-8 package layout, rail-to-rail output design implications, and validated alternative options for sensor front-ends and power-constrained analog signal chains.
Technical Context
The TLV2252AQDRG4Q1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and high input impedance (>10¹² Ω). Its CMOS input stage enables direct interfacing with high-impedance sources like piezoelectric transducers and capacitive sensors without loading error.
It operates fully specified from −40°C to +125°C with guaranteed performance at 3 V and 5 V supplies, supporting single-supply automotive systems where ground-referenced inputs and near-rail outputs are required - such as battery monitoring, cabin temperature sensing, and LIN bus interface conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports wide automotive battery range including cold-crank (≈6 V) and load-dump (up to 16 V) conditions. |
| Input Offset Voltage (max) | 850 µV at TA = 25°C - ensures <0.1% gain error in 12-bit sensor amplification with 3.3 V reference. |
| Supply Current (per channel) | 34 µA typ - enables >10-year battery life in always-on vehicle occupancy or tire pressure sensors. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - 4× lower than prior micropower CMOS op-amps, critical for low-level thermistor or strain gauge signals. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows true single-supply operation with ground-referenced inputs in 3.3 V systems. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs (e.g., ADS7822, MCP3201) without level-shifting circuitry. |
| ESD Protection | 2000 V HBM, 150 V machine model - meets automotive board-level ESD robustness requirements per ISO 10605. |
Pinout & Package
TLV2252AQDRG4Q1 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant, rated for −40°C to +125°C operation and qualified to AEC-Q100 Grade 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives low-impedance loads up to ±50 mA; rail-to-rail swing enables direct ADC connection. |
| 2 | IN1− | Inverting input of Amp 1 - high-impedance CMOS node (10¹² Ω); requires matched trace routing for noise rejection. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts common-mode voltages down to VDD−; ideal for ground-referenced sensor bridges. |
| 4 | GND / VDD− | Power return and negative supply rail - must be low-inductance plane; shared with system ground in single-supply configs. |
| 5 | IN2+ | Non-inverting input of Amp 2 - electrically identical to Pin 3; supports dual-channel sensor signal conditioning. |
| 6 | IN2− | Inverting input of Amp 2 - matches Pin 2 characteristics; enables differential measurement with matched external resistors. |
| 7 | OUT2 | Amplifier 2 output - independent rail-to-rail output; usable for feedback control loops or dual-sensor buffering. |
| 8 | VDD+ | Positive supply rail - accepts 2.7–16 V; decoupling capacitor (100 nF X7R) required within 5 mm of Pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0 V to VDD swing under 10 kΩ load - eliminates need for level-shifting when driving SAR or delta-sigma ADCs. |
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C) - certified for engine bay, cabin, and chassis-mounted electronics. |
| Ultra-low input bias current | 1 pA typical - prevents voltage error in high-Z pH electrodes, photodiode transimpedance stages, and MEMS sensor interfaces. |
| Low-noise micropower operation | 19 nV/√Hz @ 1 kHz + 34 µA/channel - achieves 16-bit-equivalent SNR in 100 Hz bandwidth with <1 µW total quiescent power. |

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 input offset voltage (vs. 850 µV), same package and pinout. | Lower precision; suitable for non-critical biasing or gain-setting where offset contributes <0.5% error. | Select when cost sensitivity outweighs 0.05% gain accuracy requirement in temperature or pressure sensing. |
| LMV722QDRQ1 | Higher supply current (120 µA/ch), wider GBW (10 MHz), but only 1.8–5.5 V supply range. | Better speed and drive capability, but incompatible with 12 V automotive systems or >5.5 V operation. | Choose for higher-bandwidth sensor interfaces (e.g., ultrasonic parking assist) where 12 V operation is not required. |
Compared with TLV2252AQDRG4Q1, TLV2252QDRQ1 trades precision for cost in stable-temperature environments, while LMV722QDRQ1 offers speed at the expense of supply voltage range and quiescent power - making TLV2252AQDRG4Q1 optimal for precision, low-power, wide-supply automotive analog front-ends.

FAQ
What is the maximum supply voltage rating for TLV2252AQDRG4Q1?
The absolute maximum supply voltage for TLV2252AQDRG4Q1 is 16 V, as specified in the Absolute Maximum Ratings table. This allows safe operation during automotive load-dump events (ISO 7637-2 Pulse 5a) without external clamping, provided power dissipation remains within the SOIC-8 derating curve (725 mW at 25°C, derated by 5.8 mW/°C).
Does TLV2252AQDRG4Q1 support true single-supply operation with ground-referenced inputs?
Yes. TLV2252AQDRG4Q1 features a common-mode input voltage range that includes the negative rail (VDD−), and its output swings rail-to-rail. When powered from 3.3 V with VDD− = GND, it accepts input signals from 0 V to 2.0 V and delivers output from 0 V to 3.3 V - enabling direct interface with ground-referenced NTC thermistors or bridge sensors.
How does the 850 µV input offset voltage specification impact precision in automotive sensor applications?
The 850 µV maximum input offset voltage at 25°C ensures minimal DC error in closed-loop configurations: for example, in a gain = 100 amplifier driving a 3.3 V ADC, it contributes only 0.026% full-scale error - well within 12-bit (0.024%) and acceptable for most 14-bit automotive sensor systems. The 0.5 µV/°C tempco further limits drift to <0.1 mV over −40°C to +125°C.
Is TLV2252AQDRG4Q1 pin-compatible with legacy TLV2322 devices?
Yes. TLV2252AQDRG4Q1 uses the same SOIC-8 pinout as TLV2322, allowing drop-in replacement in existing designs. It improves upon TLV2322 with rail-to-rail output, lower noise (19 nV/√Hz vs. 45 nV/√Hz), lower input offset voltage (850 µV vs. 2000 µV), and enhanced 125°C operation - delivering immediate performance uplift without PCB revision.
What is the typical input bias current of TLV2252AQDRG4Q1, and why does it matter in sensor interfaces?
TLV2252AQDRG4Q1 has a typical input bias current of 1 pA at 25°C, with a maximum of 60 pA. This ultra-low value prevents voltage errors across high-impedance sensor elements - for instance, in a 100 MΩ pH electrode circuit, 1 pA bias generates only 0.1 mV error, versus >10 mV with bipolar-input op-amps - preserving measurement integrity in electrochemical and capacitive sensing.
