DESCRIPTION
The L290, a monolithic LSI circuit in 16-lead inline
plastic package, is intended for user 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 controlled by
a microprocessor. The L290 integrates the follow-
ing functions:
– tacho voltage generator (F/V converter)
– reference voltage generator
– position pulse generator
