GENERAL DESCRIPTION
The TDA8926TH is the switching power stage of a
two-chip set for a high efficiency class-D audio power
amplifier system. The system is split into two chips:
TDA8926TH: a digital power stage in a HSOP24 power
package
TDA8929T: the analog controller chip in a SO24
package.
With this chip set a compact 2
× 50 W audio amplifier
system can be built, operating with high efficiency and very
low dissipation. No heatsink is required, or depending on
supply voltage and load, a very small one. The system
operates over a wide supply voltage range from
±15 up to ±30 V and consumes a very low quiescent
current.
