YDA142 DIGITAL INPUT STEREO 9.5W DIGITAL AUDIO POWER AMPLIFIER

of operating functions *Serial Audio Interface Sampling Frequency (Fs) Selection Input an audio signal using SCLK, LRCLK, and SDIN terminals. YDA142 supports three sampling frequencies (Fs): 32kHz, 44.1kHz, and 48kHz. Set the FSSEL terminal as follows in accordance with a Fs of a signal to use. .

YDA142 D- 3D DIGITAL INPUT STEREO 9.5W DIGITAL AUDIO POWER AMPLIFIER Overview YDA142 (D-3D) is a 12V single supply voltage, high-efficiency digital audio power amplifier IC. An audio power amplifier with a maximum output of 9.5W (RL=8Ω) × 2ch or 19W (RL=4Ω) × 1ch can be configured with one chip. YDA142 has a “Pure Pulse Direct Speaker Drive Circuit” that directly drives speakers while reducing distortion of a pulse output signal and reducing noise on a signal, and it realizes the highest st.
