3 Description

The OPA373 and OPA374 families of operational amplifiers are low power and low cost with excellent bandwidth (6.5 MHz) and slew rate (5 V/µs). The input range extends 200 mV beyond the rails and the output range is within 25 mV of the rails. The speed-power ratio and small size make them ideal for portable and battery-powered applications.

The OPA373 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1 µA.

The OPA373 and OPA374 families of operational amplifiers are specified for single or dual power supplies of 2.7 V to 5.5 V, with operation from 2.3 V to 5.5 V. All models are specified for –40°C to 125°C.
