Preliminary specification

70 W high efficiency power amplifier
with diagnostic facility

TDA1562Q; TDA1562ST;
TDA1562SD

FEATURES

• Fast mute on supplyvoltage drops

• Very high output power, operating from a single low
supply voltage

• Quick start option (e.g. car-telephony/navigation)

• Low power dissipation, when used for music signals

• Load dump protection

• Switches to low output power at too high case
temperatures

• Short-circuit safe to ground, supply voltage and across
the load

• Few external components

• Lowpower dissipation in any short-circuit condition

• Fixed gain

• Protected against electrostatic discharge

• Differential inputs with high common mode rejection

• Thermally protected

• Mode select pin (on, mute and standby)

• Flexible leads.

• Low (delta) offset voltage at the outputs

• Status I/O pin (class-H, class-B and fast mute)
• All switching levels with hysteresisGENERAL DESCRIPTION

• Diagnostic pin with information about:

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.

– Dynamic Distortion Detector (DDD)
– Any short-circuit at outputs

The device can be used for car audio systems (e.g.
car radios and boosters) as well as mains fedapplications
(e.g. midi/mini audio combinations and TV sound).

– Open load detector
– Temperature protection.
• No switch-on or switch-off plops
