[Communication-MobileISD1420P[1]

Description: ISD1420为美国ISD公司出品的优质单片语音录放电路,由振荡器、语音存储单元、前置放大器、自动增 益控制电路、抗干扰滤波器、输出放大器组成。一个最小的录放系统仅由一个麦克风、一个喇叭、两个按钮、一 个电源、少数电阻电容组成。录音内容存入永久存储单元,提供零功率信息存储,这个独一无二的方法是借助于 美国ISD公司的专利——直接模拟存储技术(DAST TM)实现的。利用它,语音和音频信号被直接存储,以其原 本的模拟形式进入EEPROM存储器。直接模拟存储允许使用一种单片固体电路方法完成其原本语音的再现。不 仅语音质量优胜,而且断电语音保护。
