E2U0019-28-81 ¡ Semiconductor MSM7507-01/02/03 ¡ Semiconductor Single Rail CODEC This version: Aug. 1998 MSM7507-01/02/03 Previous version: Nov. 1996 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. The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B. The analog output signal, which is of a differential type and can drive a 600 W load, can directly drive a handset receiver. FEATURES • Single power supply: +5 V ± 5% • Low power consumption Operating mode: 20 mW Typ. 40 mW Max.
