Power stage 2 x 10 or 1 x 20 W class-D

audio amplifier

Preliminary specification

TDA8928J

1 FEATURES

• High efficiency (> 90 %)

• Supply voltage from ±7.5 V to ±30 V

• Very low quiescent current

• High output power

• Diagnostic output

• Usable as a stereo Single-Ended (SE) amplifier

• Electrostatic discharge protection (pin to pin)

• No heatsink required.

3 GENERAL DESCRIPTION

The TDA8928J is a switching power stage for a high

efficiency class-D audio power amplifier system.

With this power stage a compact 2 × 10 W self oscillating

digital amplifier system can be built, operating with high

efficiency and very low dissipation. No heatsink is

required. The system operates over a wide supply voltage

range from ±7.5 V up to ±30 V and consumes a very low

quiescent current.

2 APPLICATIONS

• Television sets

• Home-sound sets

• Multimedia systems

• All mains fed audio systems.
