DESCRIPTION
LOW OFFSET: 5mV (max)
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.

SHUTDOWN: OPAx373
SPECIFIED UP TO +125°C
MicroSIZE PACKAGES: SOT23-5, SOT23-6,
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 1µA.
