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
