GENERAL DESCRIPTION
The TDA1562Q 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,
radio and boosters) as well as mains fed applications (e.g.
midi/mini audio combinations and TV sound).
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.
= 25 C; unless otherwise specified.
