audio codec conforms to the AC
’
97 2.2 and the S/PDIF
specification. The VT1612A integrates Sample Rate Converters and can be adjusted in 1Hz
increments. The analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D
surround sound effect for stereo media.
Furthermore, an integrated headphone 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 used with 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.
