L290
LINEAR INTEGRATED CIRCUIT
TACHOMETER CONVERTER
The L290, a monolithic LSI circuit in a 16-lead dual in-line plastic package, is intended for use with the
L291 and L292 which together form 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 following
functions:
- tacho voltage generator (FIV converter)
reference voltage generator
- position pulse generator.
