1.6.3VIA VT1612A Audio Codec
VIA Technologies’ VT1612ATM
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.
