The TB2924FG is an audio output IC that employs the highly efficient class D method, developed for TV and home audio applications.
The TB2924FG eliminates the need for heatsink(Note), thus allowing the design of an end product with a small footprint. It also incorporates a range of features, such as standby and muting, as well as different protective circuits.

FEATUREs
• Output: POUT = 13 W × 2ch (typ.) BTL
              VCC = 12 V, RL = 4 Ω, THD = 10%, f = 1 kHz
