2、TERS ?DRIVING A/D CONVERTERS DESCRIPTION The OPA373 and OPA374 families of operational amplifiers are low power and low cost with excellent bandwidth (6.5MHz) and slew rate (5V/s). The input range extends 200mV beyond the rails and the output range is within 25mV of the rails. Their speed/power rati
3、o 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 1A. The OPA373 and OPA374 families of operational amplifiers ar
