GENERAL DESCRIPTION
●The TDA1562 is a monolithic integrated 70 W/4 Ω 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:
● – 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 across the load
●• Low power dissipation in any short-circuit condition
●• Protected against electrostatic discharge
●• Thermally protected
●• Flexible leads.
