Audio amplifier circuit with IC TDA1562 – 70 W high efficiency power amplifier – Philips IC for automotive applications

General description
The TDA1562 is a monolithic integrated 70 W/4Ω Bridge-Tied Load (BTL) class-H high efficiency power amplifier in a 17 lead DIL-bent-SIL plastic power package.
The device can be used for car audio systems (e.g. car radios and boosters) as well as mains fed applications (e.g. midi/mini audio combinations and TV sound).

FEATURES of the IC TDA1562 – 70 W high efficiency power amplifier

  • Very high output power, operating from a single low supply voltage
  • Low power dissipation, when used for music signals
  • Switches to low output power at too high case temperatures
  • Few external components
  • Fixed gain
  • Differential inputs with high common mode rejection
  • Mode select pin (on, mute and standby)
  • Status I/O pin (class-H, class-B and fast mute)
  • All switching levels with hysteresis
  • Diagnostic pin with information about:
  • Dynamic Distortion Detector (DDD)
  • Any short-circuit at outputs
  • Open load detector
  • Temperature protection.
  • No switch-on or switch-off plops
  • Fast mute on supply voltage drops
  • Quick start option (e.g. car-telephony/navigation)
  • Low (delta) offset voltage at the outputs
  • Load dump protection
  • Short-circuit safe to ground, supply voltage and acrossthe load
  • Low power dissipation in any short-circuit condition
  • Protected against electrostatic discharge
  • Thermally protected
  • Flexible leads.
