TDA8927 TDA8929 Audio Amplifier 2x80W
TDA8927 TDA8929 Audio Amplifier 2x80W
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) 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.
TDA8927/TDA8929 applications:
- Television sets
- Home-sound sets
- Multimedia systems
- All mains fed audio systems
- Car audio (boosters).
