Overview
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.
