DESCRIPTION

The SA07 amplifier is a 40 volt, 500kHz PWM amplifier.

The full bridge output circuit provides 5 amps of con-

tinuous drive current for applications as diverse as high

fidelity audio and brush type motors. Clock output and

input pins can be used for synchronization with other

amplifiers or an externally generated clock. An inte-

grator amplifier is provided. Direct access to the pwm

input is provided for connection to digital motion con-

trol circuits. Protection circuits guard against thermal

overloads as well as shorts to supply or ground. The

current limit is programmable with one or two external

resistors depending on the application. A shutdown in-

put disables all output bridge drivers. The 18 pin steel

package is hermetically sealed.
