Product Summary
The MSM7578VM3-K is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz. The device contains filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, the device is particularly optimized for telephone terminals in digital wireless systems and ISDN systems. The MSM7578VM3-K uses the same transmission clocks as those used in the MSM7508B and MSM7509B. The analog output signal can directly drive a piezoelectric type handset receiver.
Parametrics
MSM7578VM3-K absolute maximum ratings: (1)Power Supply Voltage, VDD: 0 to 7V; (2)Analog Input Voltage, VAIN: -0.3 to VDD + 0.3V; (3)Digital Input Voltage, VDIN: -0.3 to VDD + 0.3V; (4)Storage Temperature, TSTG: -55 to +150℃.
