TACHOMETER CONVERTER
DESCRIPTION
The L290, amonolithic LSI circuit in 16-lead inline
plastic package,is intendedforuser with the L291
and L292 which together from a complete
3-chip
DC motor positioning system
for applications
such as carriage/daisy-wheel position control in
typewriters.
The L290/1/2 system can be directly controlledby
a microprocessor. The L290 integratesthe follow-
ing functions:
- tacho voltagegenerator (F/V converter)
- referencevoltage generator
- positionpulse generator
