8399 N/B Maintenance

The 20bit, ΣΔADCs VT1617/1617A implements stereo recording and white noise removal to ensure the best quality of recording. It features 8-channel hardware-expansion for flexible 7.1-channel applications. It also contains a hardware down-mixing feature that allows the end users enjoy 6-channel audio with 2-channel or 4-channel speakers. The analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D surround sound effect for stereo media. The VT1617/1617A has a built-in quality headphone amplifier and a high-accuracy PLL for cost saving. This codec is designed with aggressive power management to achieve low power consumption; when used with a 3.3V analog supply, the owner consumption is further reduced.
