Philips Semiconductors
Preliminary specication
70 W high efciency power amplier
with diagnostic facility
TDA1562Q
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.
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).
QUICK REFERENCE DATA
Test conditions: VP = 14.4 V; RL =4 ; Rs =0 ; f = 1 kHz; Tamb =25 °C; unless otherwise specied.
