Product details
Overview
TLV2252AIP from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 34 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV max input offset voltage at 25°C, enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2252AIP datasheet, TLV2252AIP pinout, TLV2252AIP application, or TLV2252AIP equivalent, key selection criteria include its rail-to-rail output swing (enabling full dynamic range with 3 V supplies), ultra-low input bias current (1 pA typ), and guaranteed performance across −40°C to 125°C for industrial and automotive sensing nodes.
Technical Context
The TLV2252AIP uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and rail-to-rail output capability without external level-shifting circuitry. Its common-mode input voltage range extends to the negative rail, supporting single-supply operation down to 2.7 V.
It features fully characterized performance at both 3 V and 5 V, with stable unity-gain operation (63° phase margin), 0.187 MHz gain-bandwidth product, and low closed-loop output impedance (220 Ω at 25 kHz), making it suitable for driving ADC inputs and low-impedance loads directly.
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 - enables accurate DC-coupled amplification in precision sensor front-ends |
| Supply Current per Channel | 34 µA typ - allows multi-channel operation in energy-constrained IoT endpoints with years of battery life |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - critical for low-level signal integrity in piezoelectric transducer and thermopile interfaces |
| Common-Mode Input Range | Includes negative rail - eliminates need for biasing resistors in single-supply configurations |
| Output Swing | Rail-to-rail - maximizes usable dynamic range when interfacing with 12-bit+ SAR ADCs |
| Input Bias Current | 1 pA typ - preserves signal fidelity in high-impedance pH, ECG, or photodiode circuits |
Pinout & Package
TLV2252AIP is housed in an 8-pin Plastic DIP (P) package with through-hole mounting and industry-standard pin spacing. The package provides mechanical robustness and thermal stability for industrial control environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA with rail-to-rail swing |
| 2 | IN−1 | Inverting input of Amp 1 - high-impedance node (10¹² Ω) for precision feedback networks |
| 3 | IN+1 | Non-inverting input of Amp 1 - accepts signals from 0 V to VDD−1.3 V at 3 V supply |
| 4 | GND / VDD− | Negative supply reference - serves as common return for both amplifiers and supports single-supply operation |
| 5 | VDD+ | Positive supply input - accepts 2.7–8 V; decoupling capacitor required near pin for stability |
| 6 | OUT2 | Amplifier 2 output - independent rail-to-rail output for dual-channel signal paths |
| 7 | IN−2 | Inverting input of Amp 2 - electrically isolated from Amp 1; no crosstalk in typical use |
| 8 | IN+2 | Non-inverting input of Amp 2 - identical electrical characteristics to IN+1 |

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 |
|---|---|---|---|
| TLV2322IP | Higher input offset voltage (1.5 mV max), higher supply current (100 µA/ch), no rail-to-rail output | Limited dynamic range with 3 V supplies; unsuitable for precision ADC driver roles | Select TLV2252AIP when rail-to-rail output and <1 mV offset are required for low-voltage accuracy |
| TLV2432IP | Higher output drive (±25 mA), wider input voltage range (to VDD−1.5 V), but 125 µA/ch supply current | Better for driving heavier loads or higher-voltage rails; trades power efficiency for drive strength | Choose TLV2252AIP for micropower priority; TLV2432IP only if >±20 mA load current is needed |
Compared with TLV2322IP and TLV2432IP, the TLV2252AIP uniquely balances rail-to-rail output, sub-millivolt offset, and micropower consumption-making it the optimal choice for battery-operated precision analog front-ends where supply headroom and quiescent current are constrained.

FAQ
What is the maximum operating temperature range for the TLV2252AIP?
The TLV2252AIP is rated for operation from −40°C to +125°C, meeting industrial and automotive-grade requirements. This specification is confirmed in the Absolute Maximum Ratings table and Recommended Operating Conditions section of the official SLOS185D datasheet, and applies to the TLV2252AIP variant packaged in the plastic DIP (P) package.
Does the TLV2252AIP support true rail-to-rail input operation?
No, the TLV2252AIP does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (GND) but stops at VDD−1.3 V for 3 V supply and VDD−1.3 V for 5 V supply. However, its rail-to-rail output swing is fully supported and specified across the entire supply range (2.7 V to 8 V).
Can the TLV2252AIP drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLV2252AIP maintains rail-to-rail output swing into 10 kΩ loads at room temperature and across its full operating temperature range. Output voltage specifications (VOH/VOL) in the datasheet are tested with RL = 100 kΩ and RL = 1 MΩ, and the device's ±50 mA short-circuit output current capability ensures robust performance well beyond 10 kΩ loads.
Is the TLV2252AIP pin-compatible with the TLV2252IP or TLV2252AID?
No - the TLV2252AIP (8-pin Plastic DIP) is not pin-compatible with TLV2252AID (8-pin SOIC) or TLV2252IP (8-pin Plastic DIP with different offset grade). While all share identical pin functions and numbering, the TLV2252AIP and TLV2252IP differ in input offset voltage spec (850 µV vs. 1500 µV max), and physical package dimensions prevent direct substitution without board revision.
What is the typical gain-bandwidth product of the TLV2252AIP at 3 V supply?
The typical gain-bandwidth product of the TLV2252AIP is 0.187 MHz at VDD = 3 V, as measured under standard test conditions (f = 1 kHz, RL = 50 kΩ, CL = 100 pF). This value remains consistent across the TLV2252AI family and is verified in the Operating Characteristics tables on page 7 of the SLOS185D datasheet.
