APPLICATIONS

DESCRIPTION

The OPA373 and OPA374 families of operational

amplifiers are low power and low cost with excellent

bandwidth (6.5MHz) and slew rate (5V/

µs). The input

range extends 200mV beyond the rails and the output

range is within 25mV 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 +2.7V to +5.5V, with operation from +2.3V to +5.5V. All

models are specified for −40

°C to +125°C.
