Single Rail CODEC

The MSM7543 and MSM7544 are single-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz. These devices contain Filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, these devices are optimized for telephone terminals in digital Wireless systems, ISDN terminals, and digital PBXs. The MSM7543 and MSM7544 use newly-designed Operational Amplifiers to maintain small current deviations caused by power-voltage fluctuations. The devices use 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 load, CAN directly drive a handset receiver.
