Overview
The OPA4374AIDRG4 is a part of the OPAx374 family of operational amplifiers (op amps) produced by Texas Instruments. These devices are known for their low power consumption, low cost, and excellent bandwidth and slew rate, making them ideal for a wide range of general-purpose applications. The OPA4374AIDRG4 is particularly suited for portable equipment, battery-powered devices, active filters, and driving A/D converters due to its rail-to-rail input and output swing and low quiescent current.
