描述 Description

GENERAL 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.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 a mono 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 switch-off plop noise
• Short-circuit proof across load and to supply lines
• Electrostatic discharge protection
• Thermally protected.APPLICATIONS
• Television sets
• Home-sound sets
• Multimedia systems
• All mains fed audio systems
• Car audio (boosters).
