Product details

Description

of operating functions Digital Amplifier Function YDA144 has digital amplifiers with analog and digital input, PWM pulse output, Maximum output of 2.1W(RL=4Ω)×2ch.Distortion of PWM pulse output signal and noise of the signal is reduced by adopting “Pure Pulse Direct Speaker Drive Circuit” In addition, YDA144 has been designed so that high-efficiency can be maintained within an average power range (100mW or so) that is used for mobile terminal.First Stage Amplifier Gain Setting Function G0

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.
