Overview
The TLV2442AIDR is a low-voltage operational amplifier from Texas Instruments, part of the Advanced LinCMOS™ family. This device is characterized by its extended common-mode input voltage range, making it suitable for a wide range of applications. It does not phase invert when the common-mode input is driven to the supply rails, and it exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLV2442AIDR is optimized for low-voltage operation and is fully characterized at 3-V and 5-V supplies.
