Preliminary data sheet
1. General
Description
The Tda8920b Is A High Ef Ciency Class-d Audio Power Ampli Er With Very Low Dissipation. The
typical output power is 2 x 100 W.
The Device Is Available In The Hsop24 Power Package And In The Dbs23p Through-hole Power Package.
The Ampli Er Operates Over A Wide Supply Voltage Range From 12.5 V To 30 V And Consumes A Very
low quiescent current.
