Overview
The OPA313IDBVR, part of the OPA313 family, is a micro-power, low-noise, rail-to-rail input and output (RRIO) operational amplifier from Texas Instruments. This device is designed for low-cost, general-purpose applications and is particularly suited for battery-powered instruments due to its low quiescent current and wide supply voltage range. The OPA313IDBVR is available in the SOT23-5 package and is optimized for operation at voltages as low as 1.8 V and up to 5.5 V, making it versatile for various consumer, industrial, and medical applications.
