GENERAL DESCRIPTION
The TDA8567Q is an integrated class-B output amplifier in
a 23-lead Single-In-Line (SIL) plastic power package.
It contains four amplifiers in BTL configuration, each with a
gain of 26 dB. The output power is 4
×
25 W in a 4
Ω
load.
APPLICATIONS
•
The device is primarily developed for car radio
applications.
