YDA144
D- 4N
STEREO 2.1W Non-Clip DIGITAL AUDIO POWER AMPLIFIER
Overview
YDA144 (D-4N) is a digital audio power amplifier IC with maximum output of 2.1W (RL=4)×2ch.
YDA144 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 YDA144 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.
