Applications
Description
The
ML7000/ML7001 are single-channel CMOS CODEC LSI devices for voice signals
ranging from 300 to 3400 Hz with filters for A/D and D/A conversion. Designed
especially for a single-power supply and low-power applications, the devices are
optimized for ISDN terminals, digital wireless systems, and digital PBXs. The
devices use the same transmission clocks as those used in the MSM7507. With the
differential analog signal outputs which can drive 600 
load, the devices can directly
drive a handset receiver.
