Description

VIA Technologies' VT1612ATM 18-bit audio codec conforms to the AC'97 2.2 and S/PDIF specifications. The VT1612A in tegrates Sample Rate Converters and can be adjustedin 1 Hz increments. The analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D surroundsoundef fect for stereo media.

Furthermore, an integratedhead phone amplifier with thermal shutdown adds signal value by reducing the BOM. This codec is designed with aggressive power management to achieve low power consumption. When usedwith a 3.3V analog supply, power consumption is further reduced. The primary applications for this part are desktop and portable personal computers multimedia subsystems. However, it is suitable for any audio subsystem requiring stereo audio input / output with S/PDIF digital output at competitive prices.
