GENERAL DESCRIPTION
The W681360 is a general-purpose single channel 13–bit linear PCM CODEC with 2s complement data format. It operates from a single +3V power supply and is available in 20-pin SOG(SOP), SSOP and TSSOP package options. The primary function of the device is the digitization and reconstruction of voice signals, including the band limiting and smoothing required for PCM systems. The W681360 performance is specified over the industrial temperature range of –40°C to +85°C.
