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  I 2C-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. Features: Differential inputs Very high Common Mode Rejection Ratio (CMRR) High common mode input signal handling Requires very few external components High output power 4 Ω and 2 Ω load driving capability Low offset voltage at output Fixed gain Diagnostic facility (distortion, short-circui...
