Car Amplifier Circuit 2 x 30 W stereo

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.

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-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
  • TDA8566TH1 is pin compatible with TDA1566TH
