TDA7272A - HIGH PERFORMANCE MOTOR SPEED REGULATOR

Datasheet Summary

Description

TDA7272A are high performance motor speed controller for small power DC motors as used in cassette players.

Using the motor as a digital tachogenerator itself the performance of true tacho controlled systems is reached.
