TDA8924
Datasheet
General description
The TDA8924 is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 x 120 W.
The device comes in a HSOP24 power package with a small internal heatsink. Depending on supply voltage and load conditions a very small or even no external heatsink is required. The amplifier operates over a wide supply voltage range from +-12.5 V to +-30 V and consumes a very low quiescent current.
Features
- High efficiency (~90 pct)
- Operating voltage from +-12.5 V to +-30 V
- Very low quiescent current
- Low distortion
- Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL)
- Fixed gain of 28 dB in SE and 34 dB in BTL
- High output power
- Good ripple rejection
- Internal switching frequency can be overruled by an external clock
- No switch-on or switch-off plop noise
- Short-circuit proof across the load and to the supply lines
- Electrostatic discharge protection
- Thermally protected.
Applications
- Television sets
- Home-sound sets
- Multimedia systems
- All mains fed audio systems
- Car audio (boosters).
