TACHOMETER CONVERTER

DESCRIPTION

The L290, a monolithic LSI circuit in 16-lead inline

plastic package,is intendedfor 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.

DIP-16 Plastic

(0.25)

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
