I am using MT8870 DTMF decoder IC in my project. I have connected the components as in the datasheet.
I have connected a mobile unit's headset also. Everything is done.
!!!!
The problem is, the ic is not at all detecting any tones and the output pins always show as follows:
STD- HIGH
Q3- Low
Q2- Low
Q1- Low
Q0- Low
Hope I find the solution asap....
Please help me
