D-4H3B
MONO 3.3W Non-Clip DIGITAL AUDIO POWER AMPLIFIER
„ General Description
YDA168B (D-4H3B) is an integrated circuit with Max.3.3W (RL=4)×1ch Class-D speaker
amplifier. This speaker amplifier uses the filter-less method allowing a speaker to be directly
connected to the output and features low-level distortion and noise characteristics.
The speaker amplifier, having Yamaha original Power Limit Interlock Non-Clip function, controls
Gain automatically and prevents output signals from being clipped at the supply voltage. In
addition, this power limit function permits the maximum output to be arbitrarily specified to 100mW
to 1000mW according to a speaker to use.
Furthermore, this amplifier has the following functions: overcurrent and overtemperature
protection functions, DC output protection function, under-voltage malfunction prevention function,
as well as EMI noise and the pop noise reduction functions and High PSRR function.
