4 x 11 W single-ended or 2 x 22 W power amplifier with distortion detector

The TDA1555Q is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) plastic power package. The circuit contains 4 x 11 W single-ended or 2 x 22 W bridge amplifiers. The device is primarily developed for car radio applications.
