Product details
Overview
TLV2252AIPW from Texas Instruments is a dual rail-to-rail output CMOS operational amplifier optimized for low-voltage, micropower applications. 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 8 V operation - enabling precision signal conditioning in battery-powered sensor interfaces and ADC front-ends.
For engineers reviewing the TLV2252AIPW datasheet, TLV2252AIPW pinout, TLV2252AIPW application, or TLV2252AIPW equivalent, this device is selected for ultra-low-power analog signal chains requiring rail-to-rail output swing, high input impedance (>10¹² Ω), and stable performance down to 3 V supply - especially where piezoelectric transducer interfacing or handheld monitoring circuitry demands minimal quiescent current and low noise.
Technical Context
The TLV2252AIPW employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low input offset voltage. Its fully differential input stage supports common-mode input voltage range extending to the negative rail, and its unity-gain-stable architecture enables direct use in single-supply configurations without external level-shifting.
Designed for low-noise, low-power operation, it features a 0.187 MHz gain-bandwidth product and 0.07–0.1 V/µs slew rate at 3 V, with phase margin of 63° and gain margin of 15 dB under standard load conditions (RL = 50 kΩ, CL = 100 pF). It is characterized across −40°C to +125°C and qualified for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3 V and 5 V systems without regulation overhead. |
| Input Offset Voltage | ≤850 µV max at 25°C - ensures <1 mV error in DC-coupled sensor amplification at room temperature. |
| Supply Current per Channel | 34 µA typ - enables multi-year battery life in always-on remote sensing nodes. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - critical for preserving SNR in high-impedance source amplification (e.g., piezo sensors). |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0 V to VDD input ranges, minimizing headroom loss. |
| Input Bias Current | 1 pA typ - prevents signal degradation in >1 MΩ source impedances, such as pH electrodes or photodiode amps. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows true single-supply operation with ground-referenced inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher input offset (2 mV max), higher noise (30 nV/√Hz), but lower cost and wider temp range (−40°C to 125°C same). | Acceptable for non-precision DC apps; unsuitable for <10 µV signal paths or low-noise sensor front-ends. | Choose when budget constraints outweigh noise/offset requirements and rail-to-rail output is not mandatory. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.5 µV/°C drift, but 17 µA higher supply current (51 µA/ch) and higher cost. | Better for high-accuracy DC measurement over temperature; less optimal for ultra-low-power battery lifetime targets. | Choose when long-term DC stability and thermal drift dominate over quiescent current in precision instrumentation. |
Compared with TLV2252AIPW, TLV2372IDR trades noise and offset for cost, while OPA2333AIDR adds zero-drift precision at the expense of micropower efficiency - making TLV2252AIPW the optimal balance for battery-operated, noise-sensitive, rail-to-rail analog front-ends.

FAQ
What is the maximum operating temperature range for the TLV2252AIPW?
The TLV2252AIPW is rated for operation from −40°C to +125°C, meeting automotive-grade thermal requirements. This range is validated per the manufacturer's recommended operating conditions and supported by characterization data across voltage and load conditions at temperature extremes.
Does the TLV2252AIPW support true single-supply operation with ground-referenced inputs?
Yes, the TLV2252AIPW supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD−/GND), and its rail-to-rail output swings from VDD− to VDD+. This eliminates need for level-shifting circuitry when interfacing with ground-referenced sensors or ADCs.
What is the typical supply current per channel for TLV2252AIPW at 3 V operation?
The TLV2252AIPW draws 34 µA per channel typical supply current at 3 V and 25°C, with a maximum of 125 µA per channel across −40°C to +125°C. This micropower consumption is confirmed in the electrical characteristics tables for both TLV2252I and TLV2252AI variants.
Can TLV2252AIPW drive capacitive loads up to 100 pF while maintaining stability?
Yes - the TLV2252AIPW is characterized for stability with 100 pF capacitive load and 50 kΩ resistive load, delivering 63° phase margin and 15 dB gain margin at unity gain. This is explicitly verified in the operating characteristics section of the datasheet under VDD = 3 V and 5 V conditions.
Is the TLV2252AIPW pin-compatible with earlier TLV2322 series op-amps?
No - the TLV2252AIPW uses an industry-standard TSSOP-8 pinout (1-IN−, 2-IN+, 3-OUT, 4-GND, 5-VDD, 6-IN−, 7-IN+, 8-OUT), whereas TLV2322IDR uses SOIC-8 with different pin assignments (e.g., Pin 1 = OUT, Pin 2 = IN−). Direct replacement requires PCB redesign.
