DESCRIPTION
The SA50 is a pulse width modulation amplifier that can sup-
ply 5A continuous current to the load. The full bridge amplifier
can be operated over a wide range of supply voltages. 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 amplifica-
tion. The SA50 is packaged in a space efficient isolated 8-pin
TO-3 that can be directly connected to a heatsink.
