TB2924FG 2-channel (BTL) Low-Frequency Power Amplifier IC

3 2006-01-25 TB2924FG Supplementary Explanation (preliminary) 1. Pin 17 (muting switch) • • • • Enable or disable audio muting. The input amplifier is switched to a dummy amplifier within the IC, so that the audio output is muted with the amplifier still operating (PWM switched operation with 50% duty ratio). Pin 17 outputs a voltage of.

Features
