The ES8156 with QFN-20-EP(3x3) ADC/DAC is a specialized and RoHS-compliant semiconductor device that is manufactured by Everest Semiconductor. This device is a low-noise, low-power stereo audio analog-to-digital converter (ADC) and digital-to-analog converter (DAC) which offers maximum signal-to-noise ratios (SNR) of more than 90 dB in both ADC and DAC applications. Additionally, ES8156 cuts down power consumption up to 40% compared with traditional microphone applications. Its sampling rate of up to 192kHz for high-definition audio processing, 24-bit resolution for digital signal processing, and 10-channel selectable differential inputs further improve audio performance. Connectors included with this product include S/PDIF, TDM, and I2S, and the package size used is a QFN-20-EP (3x3) with a 0.4mm pitch. This device is suitable for applications such as smart speaker, product recorder, camera, and medical equipment.
