TDA8922   g eneral description: The TDA8922 is a high efficiency class-D audio power amplifier with very low dissipation.  The typical output power is 2 × 25 W. The device is available in the HSOP24 power package with a small internal heatsink and in the DBS23P through-hole power package. Depending on the 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 to ±30 V and consumes a very low quiescent current. TDA8922  features : High efficiency (∼90%) Operating supply voltage from ±12.5 to ±30 V Very low quiescent current Low distortion Usable as a stereo Single-Ended (SE) amplifier or as amono amplifier in Bridge-Tied Load (BTL) Fixed gain of 30 dB in Single-Ended (SE) and 36 dB in Bridge-Tied Load (BTL) High output power Good ripple rejection Internal switching frequency can be overruled by an external clock No switch-on or swi...
