amplifier with loudspeaker protection
GENERAL DESCRIPTION
The TDA1553Q is an integrated class-B output amplifier in a 13-lead singe-in-line (SIL) plastic power package.
The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration. The device is primarily developed for
car radio applications.
