Overview
The TLV9352IDR, part of the TLV935x family from Texas Instruments, is a 40-V, cost-optimized operational amplifier designed for high-voltage, cost-sensitive applications. This device offers strong general-purpose DC and AC specifications, including 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. The TLV9352IDR is available in standard packages such as SOIC, SOT-23, TSSOP, and VSSOP, and is specified to operate over a temperature range of –40°C to 125°C.
