Overview
The TLV9354IDR, part of the TLV935x family, is a 40-V, cost-optimized operational amplifier produced by Texas Instruments. This device is designed to offer strong general-purpose DC and AC specifications, making it suitable for high-voltage, cost-sensitive applications. The TLV935x family includes the TLV9351, TLV9352, and TLV9354, each offering rail-to-rail output, low offset voltage (±350 µV typical), low offset drift (±1.5 µV/°C typical), and a bandwidth of 3.5 MHz. These op amps are available in standard packages and are specified to operate over a temperature range of –40°C to 125°C.
