DESCRIPTION
The SA50 is a pulse width modulation amplifier that can
supply 5A continuous current to the load. The full bridge
amplifier can be operated over a wide range of supply volt-
ages. All of the drive/control circuitry for the lowside and
highside switches are internal to the hybrid. The PWM circuitry
is internal as well, leaving the user to only provide an analog
signal for the motor speed/direction, or audio signal for
switchmode audio amplification. The SA50 is packaged in a
space efficient isolated 8-pin TO-3 that can be directly con-
nected to a heatsink.
