Micro Analog Systems MAS9081
The MAS9081 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. 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.| Part No. | MAS9081 |

DESCRIPTION
Only a few external components are required for time signal receiving. The control for AGC (automatic gain control) can be used to switch AGC on or off if necessary. MAS9081 supports dual band operation by switching between two crystal filters and an additional antenna tuning capacitor. MAS9081 has differential input and different internal compensation capacitor options for compensating shunt capacitances of different crystals (See ordering information on page 12).FEATURES
