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.
A dual loop control circuit provides long term stability and fast settling behaviour.
