Overview
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, circuit design with fewer external parts can be made depend on the condition of use because corresponds to filter less.
The 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 difference from the traditional AGC (Auto Gain Control) or ALC (Aut...
