DESCRIPTION
The SA160 is a pulse width modulation amplifier that
can supply 10A 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 mo-
tor speed/direction, or audio signal for switchmode
audio amplification. The internal PWM frequency can
be programmed by an external integrator capacitor.
Alternatively, the user may provide an external TTL-
compatible PWM signal for simultaneous amplitude
and direction control for four quadrant mode.
