Product Summary

The TDA8921TH is a class-D audio amplifier. Typical output power is 2 x 50 W and it operates with high efficiency and very low dissipation. The devices comes in a HSOP24 power package with a small internal heatsink. No external heatsink is required, or depending on supply voltage and load a very small one.

Parametrics

TDA8921TH absolute maximum ratings: (1)supply voltage: ±30V; (2)mode select switch voltage: 5.5V; (3)short circuit voltage of output pins: ±30V; (4)repetitive peak current in output pin: 5A; (5)storage temperature: -55 to 150℃; (6)operating ambient temperature: -40 to 85℃.

Features

TDA8921TH features: (1)Fixed gain of 30 dB in Single Ended and 36 dB in BTL; (2)High output power; (3)Good ripple rejection; (4)Internal switching frequency can be overruled by an external clock; (5)No switch-on or switch-off plop noise; (6)Short-circuit proof across the load; (7)Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load.
