Overview
The OPA317IDCKR is a member of the OPA317 family of low-power, rail-to-rail input and output operational amplifiers produced by Texas Instruments. This device is part of the Zerø-Drift family, utilizing a proprietary autocalibration technique to provide low offset voltage and near-zero drift over time and temperature. The OPA317IDCKR operates from a single or dual supply voltage range of 1.8 V to 5.5 V, making it suitable for a wide range of general-purpose applications. It is available in the SC70-5 package and is specified for operation from –40°C to +125°C.
