M7541 - Brand New Oki Semiconductor IC Chips
-
Description
The M7541 is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz. It is designed specifically for single-power supply and low-power applications, making it ideal for telephone terminals in digital wireless systems. The M7541 uses newly designed operational amplifiers that maintain small current deviations caused by power voltage fluctuations. The IC utilizes the same transmission clocks as the MSM7508B and MSM7509B and the analog output signal directly drives a piezoelectric type handset receiver.
