3 / 36 page  2001 Dec 11 3 Philips Semiconductors Preliminary specification Controller class-D audio amplifier TDA8929T 1 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). 2 APPLICATIONS • Television sets • Home-sound sets • Multimedia systems • All mains fed audio systems • Car audio (boosters). 3 GENERAL DESCRIPTION The TDA8929T 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. With this chip set a compact 2 × 50 W or 2 × 100 W audio amplifier system 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 ±30 V and consumes a very low quiescent current. 4 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA8929T SO24 plastic small outline package; 24 leads; body width 7.5 mm SOT137-1 |
