1. General description
2. Features
The TDA8566 is an integrated class-B output amplifier which is available in several
packages. TDA8566TH is contained in a 20-lead small outline plastic package. The
TDA8566TH1 is a 24-lead small outline plastic package which is pin compatible with the
I
DIL-bent-SIL package.
The device contains 2 amplifiers in a Bridge-Tied Load (BTL) configuration. The output
power is 2
and 2 diagnostic outputs. The device is primarily developed for car radio applications.
