Product details
Overview
TLV2252AIPWR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 34 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV maximum input offset voltage at 25°C, operating across 2.7 V to 8 V. It is used in battery-powered sensor signal conditioning where rail-to-rail swing interfaces with 3-V ADCs.
For engineers reviewing the TLV2252AIPWR datasheet, TLV2252AIPWR pinout, TLV2252AIPWR application, or TLV2252AIPWR equivalent, key selection criteria include micropower consumption (34 µA/channel), rail-to-rail output swing, low input bias current (1 pA typ), and guaranteed 850 µV max VIO over temperature for precision DC-coupled sensing.
Technical Context
The TLV2252AIPWR employs Advanced LinCMOS™ process technology to achieve high input impedance (>1012 Ω) and ultra-low input bias current (1 pA typ). Its rail-to-rail output stage enables full dynamic range utilization in single-supply systems down to 2.7 V.
It features fully characterized performance at both 3 V and 5 V, with common-mode input voltage range extending to the negative rail and specified operation from −40°C to 125°C. The device supports stable unity-gain operation with 63° phase margin and 15 dB gain margin into 50 kΩ || 100 pF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct use with single-cell Li-ion (3.0–3.7 V), two-cell alkaline (2.4–3.2 V), or regulated 3.3/5 V rails. |
| Supply Current per Channel | 34 µA typ - Supports multi-year battery life in always-on remote sensors and portable medical monitors. |
| Input Offset Voltage | 850 µV max at 25°C - Ensures <0.1% error in 1-V full-scale bridge amplifier or thermopile front-ends without trimming. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - Critical for preserving SNR in low-level piezoelectric or strain gauge signal chains. |
| Common-Mode Input Range | Includes negative rail (VDD−/GND) - Allows direct interfacing with ground-referenced transducers without level-shifting circuitry. |
| Output Swing | Rail-to-rail - Delivers >99% of supply voltage swing, maximizing ADC utilization in 3-V systems. |
| Gain-Bandwidth Product | 0.187 MHz at 3 V - Sufficient for anti-aliasing filters, sensor amplification, and DC-coupled instrumentation up to ~100 kHz. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - Drives low-impedance loads up to ±50 mA; rail-to-rail swing ensures full ADC input range coverage. |
| 2 | IN−1 | Inverting input of Amp 1 - High-impedance node (>1012 Ω); requires guarded layout for pA-level bias current integrity. |
| 3 | IN+1 | Non-inverting input of Amp 1 - Accepts signals from 0 V to VDD−1.3 V; extends to negative rail for true single-supply operation. |
| 4 | GND / VDD− | Negative supply / ground reference - Shared return path for both amplifiers; must be low-impedance to avoid crosstalk. |
| 5 | VDD+ | Positive supply - Powers both amplifiers; bypass capacitor (0.1 µF) required within 5 mm for stability. |
| 6 | IN−2 | Inverting input of Amp 2 - Independent of Amp 1; enables dual-channel differential sensing or signal splitting. |
| 7 | IN+2 | Non-inverting input of Amp 2 - Matches Amp 1 specs; supports independent gain stages or active filtering paths. |
| 8 | OUT2 | Amplifier 2 output - Electrically isolated from OUT1; allows simultaneous processing of two analog channels. |
Key Features

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 |
|---|---|---|---|
| TLV2372IDR | Higher input offset voltage (2 mV max), higher supply current (20 µA/channel), no rail-to-rail output (swing limited to VDD−0.7 V). | Suitable for cost-sensitive, non-precision applications where rail-to-rail swing is not required. | Select TLV2252AIPWR when rail-to-rail output and sub-millivolt offset are mandatory; TLV2372IDR only if budget constraints outweigh performance needs. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 17 µA/channel, rail-to-rail I/O, but higher noise (57 nV/√Hz) and narrower supply range (1.8–5.5 V). | Better for ultra-low-offset DC applications (e.g., precision weigh scales), but less optimal for low-noise AC-coupled sensing. | Choose TLV2252AIPWR for balanced low-noise, low-power, rail-to-rail performance; OPA2333AIDR only when near-zero drift dominates system requirements. |
Compared with TLV2372IDR and OPA2333AIDR, the TLV2252AIPWR uniquely combines rail-to-rail output, 850 µV max offset, and 19 nV/√Hz noise at 34 µA/channel-making it optimal for battery-powered precision analog front-ends where dynamic range, DC accuracy, and noise co-constrain design.

FAQ
What is the maximum operating temperature range for the TLV2252AIPWR?
The TLV2252AIPWR is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This rating is confirmed in the Absolute Maximum Ratings table and Recommended Operating Conditions section of the official SLOS185D datasheet, with full electrical characterization across this range for parameters including input offset voltage and supply current.
Does the TLV2252AIPWR support true single-supply operation with inputs referenced to ground?
Yes, the TLV2252AIPWR supports true single-supply operation: its common-mode input voltage range includes the negative rail (GND), and the input stage operates down to VDD−. Per the datasheet, VICR extends to VDD− at 25°C and maintains usable performance to VDD− across the full temperature range, enabling direct connection of ground-referenced transducers without level-shifting circuitry.
What is the typical supply current per channel for the TLV2252AIPWR at 3 V?
The typical supply current per channel for the TLV2252AIPWR is 34 µA at VDD = 3 V and TA = 25°C, as specified in the "Electrical Characteristics" tables for TLV2252AI under 3-V conditions. This value remains stable across the full −40°C to +125°C range, with a maximum of 150 µA per channel over temperature.
Is the TLV2252AIPWR pin-compatible with other devices in the TLV225x family?
Yes, the TLV2252AIPWR shares identical pinout and footprint with all TLV2252 variants in TSSOP-8 (PW) packaging, including TLV2252IDR and TLV2252QDR. Pin assignments (OUT1, IN−1, IN+1, GND, VDD+, IN−2, IN+2, OUT2) are standardized across the family, enabling drop-in replacement where temperature grade and offset specifications align.
What load capacitance does the TLV2252AIPWR drive stably in unity-gain configuration?
The TLV2252AIPWR is characterized for stable unity-gain operation with a capacitive load of up to 100 pF when driving into a 50 kΩ resistive load, as verified by 63° phase margin and 15 dB gain margin in the Operating Characteristics tables. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability.
