DESCRIPTION

The LM628/LM629 are dedicated motion-control

processors designed for use with a variety of DC and

brushless DC servo motors, and other

servomechanisms which provide a quadrature

incremental position feedback signal. The parts

perform the intensive, real-time computational tasks

required for high performance digital motion control.

The host control software interface is facilitated by a

high-level command set. The LM628 has an 8-bit

output which can drive either an 8-bit or a 12-bit

DAC. The components required to build a servo

system are reduced to the DC motor/actuator, an

incremental encoder, a DAC, a power amplifier, and the LM628. An LM629-based system is similar,

except that it provides an 8-bit PWM output for

directly driving H-switches. The parts are fabricated in

NMOS and packaged in a 28-pin dual in-line package

or a SOIC-24 package (LM629 only). Both 6 MHz and

8 MHz maximum frequency versions are available

with the suffixes -6 and -8, respectively, used to

designate the versions. They incorporate an SDA

core processor and cells designed by SDA.
