2 x 120 W Class D power amplifier

Leave a Comment
FEATURES:

High efficiency (∼90 %)
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).

GENERAL DESCRIPTION:

The TDA8924 is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 × 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.
