Product Summary
The TDA8920TH is a high efficiency class-D audio power amplifier. Typical output power is 2 x 80W and it operates with high efficiency and very low dissipation. 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 卤12.5 up to =+30 V and consumes a very low quiescent current.
Parametrics
Absolute maximum ratings: (1)Vp, supply voltage: 卤30 V max; (2)Vms, mode select switch voltage with respect to SGND: 5.5 V max; (3)Vsc, short circuit voltage of output pins: 卤 30 V max; (4)IORM, repetitive peak current in output pin: 7.5 A max; (5)Tstg, storage temperature: -55 to +150 鈩? (6)Tamb, operating ambient temperature: -40 to +85 鈩? (7)Tvj, virtual junction temperature: 150 鈩?max.
Features
Features: (1)High efficiency (~90%); (2)Operating voltage from 卤12.5 V to + 30V; (3)Very low quiescent current; (4)Low distortion; (5)Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL); (6)Fixed gain of 30 dB in Single Ended (SE) and 36 dB in Bridge-Tied-Load (BTL); (7)High output power; (8)Good ripple rejection; (9)Internal switching frequency can be overruled by an external clock; (10)No switch-on or switch-off plop noise; (11)Short-circuit proof across the load; (12)Electrostatic discharge protection; (13)Thermally protected.
