STMicroelectronics TDA7272A
The TDA7272A novel applied solution is based time for motors with a low number of poles. The on a tachometer control system without using realized circuit is extended by a second feed forsuch extra tachometer system. The information of ward loop in order to improve such system by a the actual motor speed is extracted from the mofast auxiliary control path.| Part No. | TDA7272A |

DESCRIPTION
TDA7272A are high performance motor speed controller for small power DC motors as used in cassette players. BLOCK DIAGRAM Powerdip(16+2+2) ORDERING NUMBER: TDA7272A 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. This is advanced information on a new product now in development or undergoing evaluation.
