Philips Electronics 

Philips Semiconductors

2 × 40 W/2 Ω stereo BTL car radio power amplifier

with differential inputs and diagnostic outputs

Objective specification

TDA8566TH

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 and 2 Ω load driving capability

• Low offset voltage at output

• Fixed gain

• Diagnostic facility (distortion, short-circuit and

temperature pre-warning)

• Good ripple rejection

• Mode select switch (operating, mute and standby)

• Load dump protection

• Short-circuit proof to ground, to VP and across the load

• Low power dissipation in any short-circuit condition

• Thermally protected

• Reverse polarity safe

• Protected against electrostatic discharge

• No switch-on/switch-off plops

• Low thermal resistance.

GENERAL DESCRIPTION

The TDA8566TH is an integrated class-B output amplifier

contained in a 20-lead small outline plastic 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.
