D-4N

STEREO 2.1W Non-Clip DIGITAL AUDIO POWER AMPLIFIER

■Overview

YDA144B (D-4N) is a digital audio power amplifier IC with maximum output of 2.1W (R_L=4Ω)×2ch.

YDA144B has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of

pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate characteristics

and low noise characteristics among digital amplifier ICs for mobile use.

In addition, circuit design with fewer external parts can be made depend on the condition of use because corresponds to

filter less.

The YDA144B features Yamaha original non-clip output control function which detects output signal clip due to the over

level input signal and suppress the output signal clip automatically. Also the non-clip output control function can adapt

the output clip caused by power supply voltage down with battery. This is the difference from the traditional AGC (Auto

Gain Control) or ALC (Auto Level Control) circuit. Attack time and release time can be freely set by external resistances

or capacitances.

The independent power-down function for L channel and R channel minimizes consumption current at standby. As for

protection function, overcurrent protection function for speaker output terminal, overtemperatue protection function for

inside of the device, and low supply voltage malfunction preventing function are prepared.
