... TP3054-X, TP3057-X Extended Temperature Serial Interface CODEC/Filter COMBO ® Family General Description The TP3054, TP3057 family consists of µ-law and A-law monolithic PCM CODEC/filters utilizing the A/D and D/A conversion architecture shown in Figure 1, and a serial PCM interface. The devices are fabricated using National’s ad- vanced double-poly CMOS process (microCMOS) ...
