I am making a device that playback some presaved massages.
My poject is microcontroller based and i use PIC16F877 as controller and ISD25120 as voice recorder/playback .
becouse of learning of ISD25120 ,At first I assembled it AS KEY MODE(according of ISD25129 DATASHEET)but HAVE A PROBLEM:
The output power is very low and the playback voice is very weak.
I want to know is there any problem by MY circuit,
or this is normal by ISD25120 and AMPLIFIERING is neccessary after this chip.
Pls kindly contact me.
Thanks! Hope to hear you soon!
