TDA8927/TDA8929  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 SO24package. With this chip set a compact 2 × 80 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 quiescentcurrent. TDA8927/TDA8929  features: High efficiency (>94%) Operating voltage from ±15 to ±30 V 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) amp...
