KA301A
Single Operational Amplifier
Features
•
•
•
•
Short circuit protection and latch free operation
Slew rate of 10V/µs as a summing amplifier
Class AB output provides excellent linearity
Low bias current
Description
The KA301A is a general purpose operational amplifier
which is externally phase compensated, permit a choice of
operation for optimum high frequency performance at a
selected gain: unity gain compensation can be obtained with
a single capacitor.
