Digital Voice Recorder ISD2560

 


This project is based on ISD2560P IC which allows us to record 60 seconds voice and playback it with very high quality. As shown in the schematic, we input the voice by using an electret microphone. If a dynamic microphone is used, R2,R3,R4 resistors and C3,C5,C7 capacitors will be omitted and microphone will be connected to 17 and 18 numbered pins directly. Since it has better frequency response, we choose electret microphone in this project.
