W682510S Datasheet



The W682510 and W682310 are general-purpose dual channel PCM CODECs with pin-selectable μ-Law or A-Law companding. The device is compliant with the ITU G.712 specification. It operates from a single power supply (+5V for the W682510, +3V for the W682310) and is available in 20-pin PDIP (W682510 only), SSOP, and 24-pin SOP package options. Functions performed include digitization and reconstruction of voice signals, and band limiting and smoothing filters required for PCM systems. The filters are compliant with ITU G.712 specification. The W682510 and W682310 performance is specified over the industrial temperature range of –40°C to +85°C.
