TDA8929T

Controller class-D audio amplifier

GENERAL DESCRIPTION

The is the controller of a two-chip set for a high efficiency class-D audio power amplifier system. The system is divided into two chips:

• TDA8929T; the analog controller chip in a SO24 package

• TDA8926J/ST/TH or TDA8927J/ST/TH; a digital power stage in a DBS17P, RDBS17P or HSOP24 power package.

FEATURES

• Operating voltage from±15 to±30 V

• Very low quiescent current

• Low distortion

• Fixed gain of 30 dB Single-Ended SE or 36 dB Bridge-Tied Load BTL

• Good ripple rejection

• Internal switching frequency can be overruled by an external clock

• No switch-on or switch-off plop noise

• Diagnostic input for short-circuit and temperature protection

• Usable as a stereo Single-Ended SE amplifier or as a mono amplifier in Bridge-Tied Load BTL

• Start-up safety test, to protect for short-circuits at the output of the power stage to supply lines

• Electrostatic discharge protection pin to pin.
