PCM Voice Codec
Version 1.00, June 1998
Preliminary
GENERAL DESCRIPTION
The ML7000 (for +5V)/ML7001(for +3V) are single channel CMOS CODEC LSIs containing A/D and D/A
conversion filters for voice signals ranging from 300Hz to 3400Hz. These LSIs feature single-rail power supply and
low power consumption and are suitable for ISDN systems, digital wireless systems, digital PBX, etc. As for ana-
logue output, ML7000-xx and ML7001-xx are able to drive a receiver handset directly.
