GENERAL DESCRIPTION
The TDA1562 is a monolithic integrated 70 W/4 ⦠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
⢠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:
â Dynamic Distortion Detector (DDD)
â Any short-circuit at outputs
â Open load detector
â 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 across the load
⢠Low power dissipation in any short-circuit condition
⢠Protected against electrostatic discharge
⢠Thermally protected
⢠Flexible leads.
