GENERAL DESCRIPTION
The TDA8927 is the switching power stage of a two-chip set for a high efficiency class-D audio power amplifier system. The system is split into two chips:
• TDA8927J/ST/TH; a digital power stage in a DBS17P,RDBS17P or HSOP24 power package
• TDA8929T; the analog controller chip in a SO24 package.

With this chip set a compact 2×80 W audio amplifiersystem can be built, operating with high efficiency and very low dissipation. No heatsink is required, or depending on supply voltage and load, a very small one. The system operates over a wide supply voltage range from ±15 up to ±30V and consumes a very low quiescent current.

FEATURES
• High efficiency (>94%)
• Operating voltage from±15 to ±30V
• Very low quiescent current
• High output power
• Short-circuit proof across the load, only in combination with controller TDA8929T
• Diagnostic output
• Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL)
• Electrostatic discharge protection (pin to pin)
• Thermally protected, only in combination with controller TDA8929T.

APPLICATIONS
• Television sets
• Home-sound sets
