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=4Ω)×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.

Quick Start/Quick Mute Function
Pop noise reduction circuit (Quick Start/Quick Mute） operates at startup or shutdown of the
speaker amplifier.
This is a function to vary ON/OFF envelopes at a slow rate. Even a high-speed ON/OFF operation,
this reduces intermittent sound considerably and eliminates uncomfortable feeling.
That is, Quick Start/Quick Mute is a pop noise reduction function with Non-Clip technique applied.
