DESCRIPTION
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 for time signal receiver. The circuit has preamplifier,wide range automatic gain control, demodulator and 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.
MAS6180  has  options  for  compensating  shunt capacitances  of  different  crystals  (See  ordering information on page 9).
