ISD1420P

The ISD1420P is one member of the ISD1400 series which designed as one kind of single-chip voice record/playback devices.It provides high-quality,single-chip record/playback solutions to short-duration messaging applications.This series of devices include an on-chip oscillator,microphone preamplifier,auto-matic gain control,antialiasing filter,smoothing filter and speaker amplifier.A minimum record/playback subsystem can be configured with a microphone,a speaker,several passives,two push-buttons and a power source.

Features of the ISD1420P are:(1)easy-to-use single-chip voice record/playback solution;(2)high-quality,natural voice/audio reproduction;(3)single-chip durations of 16 and 20 seconds;(4)fully addressable to handle multiple messages;(5)100-year message retention (typical);(6)100000 record cycles (typical);(7)on-chip clock source;(8)single +5 volt power supply;(9)available in die form,DIP and SOIC packaging.

The absolute maximum ratings of the ISD1420P can be summarized as:(1)junction temperature:150 ;(2)storage temperature range:-65 to +150;(3)voltage applied to any pin:(Vss-0.3V) to (Vcc+0.3V);(4)lead temperature(soldering-10 seconds):-0.3V to +7.0V.If you want to know more information such as the electrical characteristics about the ISD1420P,please download the datasheet in www.seekic.com or www.chinaicmart.com .
