GENERAL 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 60 W load, the devices can directly drive a handset receiver.

FEATURES

• Single power supply: +5 V (ML7000-xx)

+3 V (ML7001-xx)

• Low power consumption

Operating mode: 25 mW Typ. VDD = 5.0 V (ML7000-xx)

20 mW Typ. VDD = 3.0 V (ML7001-xx)

Power-down mode: 0.05 mW Typ. VDD = 5.0 V (ML7000-xx)

0.03 mW Typ. VDD = 3.0 V (ML7001-xx)

• Conforms to ITU-T Companding law
