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.

PORTABLE EQUIPMENT  
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.
