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 1µA.
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.
