GENERAL DESCRIPTION
The TDA8568Q is a integrated class-B output amplifier in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in BTL configuration, each with a gain of 40 dB. The output power is 4 × 25 W in a 4 Ω load.
FEATURES
• Requires very few external components
• High output power
• Low output offset voltage
• 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 safe to ground and to VP and across the load
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Electrostatic discharge protection
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance
• Pin compatible with the TDA8567Q, except for the gain.
APPLICATIONS
• The device is primarily developed for car radio applications.
