... MSM7507-01/02/03 Single Rail CODEC GENERAL DESCRIPTION The MSM7507 is a single-channel CODEC CMOS IC 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 device is optimized for ISDN terminals, digital wireless systems, and digital PBX systems. ...

... ALAW Control signal input of the companding law selection. Provides only for the MSM7507-01GS-K/7507-01MS-K. The CODEC will operate in the m-law when this pin logic "0" level and the CODEC will operate in the A-law when this pin logic "1" level. The CODEC operates in the m-law if the pin is left open, since the pin is internally pulled down ...
