Product details
Overview
TLV2262IPW from Texas Instruments is a dual rail-to-rail output CMOS operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage (at 25°C), 12 nV/√Hz input voltage noise at 1 kHz, and 500 µA max supply current per amplifier across 2.7 V to 8 V supply range - enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2262IPW datasheet, TLV2262IPW pinout, TLV2262IPW application, or TLV2262IPW equivalent, key selection criteria include its rail-to-rail output swing, sub-1 pA input bias current, wide common-mode input range extending to the negative rail, and guaranteed performance at 3 V and 5 V for portable and industrial analog front-ends.
Technical Context
The TLV2262IPW implements a CMOS input stage with high-impedance differential pair architecture, supporting single-supply operation down to 2.7 V while maintaining rail-to-rail output capability. Its input stage includes ESD protection and trim circuitry for stable offset over temperature.
It features a unity-gain-stable design with 0.67 MHz gain-bandwidth product (at 3 V) and 0.3 V/µs slew rate, optimized for low-noise small-signal amplification without compromising power efficiency - distinguishing it from both micropower (TLV225x) and higher-speed (TLC227x) families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| Input Offset Voltage | 950 µV max at 25°C - enables DC-coupled precision amplification of mV-level sensor outputs. |
| Input Bias Current | 1 pA typ - preserves signal integrity when interfacing with high-impedance sources like piezoelectric transducers. |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving SAR or delta-sigma ADCs with limited reference headroom. |
| Supply Current | 500 µA max per amplifier - allows dual-channel operation in ultra-low-power handheld devices. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - suitable for amplifying low-amplitude signals without significant noise degradation. |

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 |
|---|---|---|---|
| TLV2262AIPWLE | Same package and pinout; tighter 950 µV max input offset (vs. 2.5 mV for TLV2262IPW). | Required where DC accuracy dominates over cost in precision sensor signal chains. | Select TLV2262AIPWLE when offset drift and long-term stability are critical; TLV2262IPW remains optimal for general-purpose low-power amplification. |
| TLV2332IPW | Legacy dual op-amp with higher 2.5 mV offset, 1.5 V/µs slew rate, and no rail-to-rail output. | Used in legacy designs where output swing beyond 1 V from rails is acceptable. | TLV2262IPW upgrades TLV2332IPW with improved noise, lower offset, and rail-to-rail output - ideal for redesigns targeting enhanced dynamic range. |
Compared with TLV2262AIPWLE, TLV2262IPW trades guaranteed offset performance for broader availability and cost efficiency; versus TLV2332IPW, it delivers superior AC performance, lower noise, and full rail-to-rail output - making it the preferred choice for new low-voltage analog front-end designs requiring precision and power efficiency.

FAQ
What is the maximum operating temperature range for the TLV2262IPW?
The TLV2262IPW is rated for operation from −40°C to +125°C, meeting industrial temperature requirements. This specification is confirmed in the Absolute Maximum Ratings table and Recommended Operating Conditions section of the official SLOS186C datasheet, where the "I suffix" denotes this extended range.
Does the TLV2262IPW support true rail-to-rail input operation?
No, the TLV2262IPW does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ −1.3 V at 3 V supply - meaning it cannot accept inputs at the positive rail. This is explicitly specified in the Recommended Operating Conditions table under VICR.
What is the typical supply current consumption of the TLV2262IPW at 3 V?
The TLV2262IPW draws 400 µA typical and 500 µA maximum supply current per amplifier at 3 V, as documented in the Electrical Characteristics tables for VDD = 3 V. Total device current is therefore 800 µA typical and 1000 µA maximum for both amplifiers active.
Can the TLV2262IPW drive capacitive loads directly?
The TLV2262IPW is unity-gain stable with up to 100 pF capacitive load when configured with RL = 50 kΩ, as verified in the Operating Characteristics tables. Driving larger capacitive loads requires isolation resistance or external compensation to maintain phase margin above 55°.
Is the TLV2262IPW pin-compatible with other TSSOP-8 dual op-amps from Texas Instruments?
Yes, the TLV2262IPW uses the industry-standard TSSOP-8 pinout for dual op-amps (SO-8 compatible mapping), matching pin assignments of TLV2332IPW, TLV2432IPW, and TLV2772IPW. This allows drop-in replacement in many existing layouts, though electrical performance differences must be validated per application.
