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. Their speed/power ratio
and small size make them ideal for portable and
battery-powered applications.
