Overview
The OPA374AIDBVRG4 is a part of the OPAx374 family of operational amplifiers produced by Texas Instruments. These low-power, low-cost operational amplifiers are known for their excellent bandwidth of 6.5 MHz and a high slew rate of 5 V/µs. The OPA374AIDBVRG4 is particularly suited for applications requiring rail-to-rail input and output, making it ideal for single-supply operations ranging from 2.3 V to 5.5 V. The device is available in various microsize packages, including the 5-pin SOT-23 package, which is compact and suitable for portable and battery-powered devices.
