详细描述

MAS6180 AM 接收器芯片是一种高灵敏度、易于使用的 AM 接收器，专门用于接收 40 kHz 至 100 kHz 频率范围内的时间信号。只需要几个外部组件。该电路内置前置放大器、宽范围自动增益控制、解调器和输出比较器。输出信号可以直接由附加数字电路处理，以从接收信号中提取数据。如有必要，AGC（自动增益控制）控件可用于打开或关闭 AGC。

The MAS6180 AM-Receiver chip is a highly sensitive, simple to use AM receiver specially intended to receive time signals in the frequency range from 40 kHz to 100 kHz. Only a few external components are required. The circuit has a preamplifier, wide range automatic gain control, demodulator and an output comparator built in. The output signal can be processed directly by an additional digital circuitry to extract the data from the received signal. The control for AGC (automatic gain control) can be used to switch AGC on or off if necessary.
