DESCRIPTION

The SA56 is a 5A PWM Ampliﬁer designed for motion con-

trol applications. The device is built using a multi-technology

process which combines bipolar and CMOS control circuitry

with DMOS power devices in the same monolithic structure.

Ideal for driving DC and stepper motors; the SA56 accom-

modates peak output currents up to 10A. An innovative circuit

which facilitates low-loss sensing of the output current has

beenimplemented. OnboardPWMoscillatorandcomparator

are used to convert an analog signal into PWM direction and

magnitude for motor control applications, or to amplify audio

signals using class D ampliﬁcation.
