Product Summary

The AM79C02AJC Dual Subscriber Line Audio Processing Circuit (DSLAC device) integrates the key functions of an analog linecard into a single high-performance, programmable dual codec/filter device. The DSLAC device is based on the proven design of thereliable AM79C02AJC Subscriber Line Audio Processing Circuit (SLAC device) . The advanced CMOS technology of the AM79C02AJC makes this an economical device that has both the functionality and the low power conumption needed in line card designs to maximize linecard density at minimum cost.
