GENERAL DESCRIPTION
The TDA8566Q is an integrated class-B output amplifier contained in a 17-lead single-in-line (SIL; bent to DIL) plastic power package. The device contains two amplifiers in a Bridge-Tied Load configuration (BTL). The output power is 2×25 W in a 4Ωload or 2 ×40 W in a 2Ω load. It has a differential input stage and two diagnostic outputs. The device is primarily developed for car radio
applications.
