Overview
The OPA4180IPWR is a high-precision, quad-channel operational amplifier (op amp) produced by Texas Instruments. This device utilizes TI's proprietary zero-drift techniques to provide low offset voltage and near zero-drift over time and temperature. It is designed for applications requiring high DC precision, low noise, and a wide supply range. The OPA4180IPWR is available in a TSSOP-14 package and is specified to operate over a temperature range of –40°C to +125°C.
