Product Summary

The ISD1730P is a high quality, fully integrated, single-chip multi-message voice record and playback device ideally suited to a variety of electronic systems. The ISD1730P message duration is user selectable in ranges from 26 seconds to 120 seconds, depending on the specific device. The sampling frequency of the ISD1730P can also be adjusted from 4 kHz to 12 kHz with an external resistor, giving the user greater flexibility in duration versus recording quality for each application. Operating voltage spans a range from 2.4 V to 5.5 V to ensure that the ISD1730P is optimized for a wide range of battery or line-powered applications.
