1. General description
2. Features
The TDA1566 is a car audio power amplifier with a complementary output stage realized
in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a
HSOP24 or DBS27P package.
The TDA1566 can be controlled with or without I
per channel and diagnostic trigger levels can be selected. Failure conditions as well as
load identification can be read with I
outputs of a BTL channel are connected with a DC or AC load and discriminates between
a speaker load, a line driver load and an open (unconnected) load.
The TDA1566 can be configured in a single BTL mode and drive a 1
BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of
both BTL channels in parallel.
