Hi Rickey,
If you use the Mic input, it will work. A simple condenser mic (available at Radio Shack) will do fine.
If you need to use the AnaIn (pin9) input, then FT (pin22) must be held low during recording. It will then record from the analog input.
The ISD2500 series was much easier to use in pushbutton mode, but it has been discontinued.
The Winbond website and the ISD1700 datasheet frequently say "For technical details, please refer to the Design Guide". That is NOT the "AN-CC1002 Design Considerations for ISD1700 Family.pdf" document that is available on their website! In order to get the "Design Guide" (I1700 Design Guide Rev 1.1.pdf) I had to email them and request it. That is the only document I've found that bothers to tell you that the devices come from the factory with the AnaIn input and the Aux (Voltage) output disabled in pushbutton mode.
In order to reprogram the device's analog path configuration, you need to use the SPI interface. If you need more info on that, or have any other questions, let me know.
