Description
ALC202E is a single chip audio CODEC of the IC chip category with a high S/N ratio (>90 dB). It has a 20-bit DAC and an 18-bit ADC. This stereo full-duplex CODEC comes with independent and variable sampling rates. The ALC202E supports 4 analog line-level stereo inputs with 5-bit volume control, 2 analog line-level mono inputs: PC_BEEP, PHONE_IN. It also provides a mono output with 5-bit volume control and a stereo output with 6-bit volume control. Further, the ALC202E supports 2 MIC inputs, 3D Stereo Enhancement, and a jack-detect function to mute LINE/MONO/HP output, to control S/PDIF output. Moreover, it has +30dB boost preamplifier for MIC input. The digital support is 3.3V and the analog support is 3.3V/5V. The standard 48-Pin LQFP Package makes it easy to install. Overall, the Realtek ALC202E is a good choice for those seeking high-quality audio CODEC.
