2 × 40 W/2 Ω stereo BTL car radio power amplifier with
differential inputs and diagnostic outputs
Rev. 06 — 15 October 2007
Product data sheet
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 2 amplifiers in a Bridge-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.
