Hi there,
I'm going to use a ISD1110P chipcorder for a project. I will record 5 sample of 2s length. I will not be using an electret microphone. Instead, I will be using the ANALOG IN pin of the ISD.
I have a couple questions, maybe you could help me to sort that out.
When not in use, ANA-In is connected to ANA-OUT through a resistor and a capacitor.
I will not be using ANA-OUT, what should I do with the ANA-OUT pin, leave it floating?
As I will not be using Microphone as an input, What should I do with the following pins: MIC, MIC REF and AGC? leave them floating?
It will be very kind if someone could give some advice about that.
Thank you in andvance for any clue.
