Product Summary

The MC145506P is a PCM Codec-Filter Mono-circuit. The MC145506P performs the voice digitization and reconstruction, as well as the band limiting and smoothing required for PCM systems. It has HCMOS compatible digital outputs and otherwise supplement. The MC145506P is functionally similar to the MC145502, MC145503, and MC145505, respectively. It is designed to operate in both synchronous and asynchronous applications and contain an on–chip precision reference voltage. The MC145506P is offered in a 22–pin package and has the capability of selecting from three peak overload voltages (2.5 V, 3.15 V, and 3.78 V).
