www.ti.com SNVS781C – JUNE 1999 – REVISED MARCH 2013 LM628/LM629 Precision Motion Controller
Check for Samples: LM628, LM629 FEATURES 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 …
