TDA8926TH
General description
The TDA8926TH 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:
- TDA8926TH: a digital power stage in a HSOP24 power package
- TDA8929T: the analog controller chip in a SO24 package.
With this chip set a compact 2 x 50 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.
Features
- High efficiency (>94pct)
- 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)
- Standby mode
- Electrostatic discharge protection (pin to pin)
- Thermally protected, only in combination with controller TDA8929T.
Applications
- Television sets
- Home-sound sets
- Multimedia systems
- All mains fed audio systems
- Car audio (boosters).
