Philips TDA8566 manual

1. General description

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

I2C-bus controlled ampliﬁer TDA1566TH for one board layout. TDA8566Q is a 17-pin

DIL-bent-SIL package.

The device contains 2ampliﬁers in a Br idge-Tied Load (BTL) conﬁguration. The output

power is 2 ×25 W in a 4 Ω load or 2 ×40 W in a 2 Ω load. It has a differential input stage

and 2 diagnostic outputs. The device is primarily developed for car radio applications.
