Note: The CS3524A should be able to be tested in any 3524 test circuit with two possible exceptions:

1. The higher gain-bandwidth of the current limit amplifier in the CS 3524A may cause oscillations in an uncom-

pensated 3524 test circuit.

2. The effect of the shutdown, cannot be seen at the compensation terminal, but must be

observed at the outputs.
