MSM7508B - (MSM7509B) Single Rail CODEC
The MSM7508B and MSM7509B 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 ISDN a
