YDA145 Datasheet Monaural 2.1w Non-clip Digital Audio Power Amplifier

Manufacturer: YAMAHA CORPORATION

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.
