YDA145 MONAURAL 2.1W Non-Clip DIGITAL AUDIO POWER AMPLIFIER

of operating functions *Digital Amplifier Function YDA145 has digital amplifiers with analog input, PWM pulse output, and maximum output of 2.1W(RL=4Ω)×1ch. Distortion of PWM pulse output signal and noise of the signal is reduced by adopting “Pure Pulse Direct Speaker Drive Circuit”. In addition.

YDA145 D- 4H MONAURAL 2.1W Non-Clip DIGITAL AUDIO POWER AMPLIFIER Overview YDA145 (D-4H) is a digital audio power amplifier IC with maximum output of 2.1W (RL=4Ω)×1ch. YDA145 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, c.

YDA145 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 di
