The W682310 is a dual channel PCM CODEC with pin-selectable µ-Law or A-Law companding according to ITU G.711 and G.712. It has a built-in PLL which eliminates the need for a master clock. The analog section is fully differential, reducing noise and improving the power supply rejection ratio. The analog output is non-inverted.
The device operates off a single +3V power supply and is available in SOP-24 and SSOP-20 package options.
