NOTES:
*
Pin identifications for the ISD2532/40/48/64 devices which differ from those of the ISD2560/75/90/120 devices are
indicated.
** If desired, pin 18 (PDIP package) may be left unconnected (microphone preamplifier noise will be higher). In this case,
pin 18 must not be tied to any other signal or voltage. Additional design example schematics are provided in the
Application Notes and Design Manual in this book.
