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.
