AM Receiver IC
• High Sensitivity
• Very Low Power Consumption
• Wide Supply Voltage Range
• Power Down and Power Up Control
• High Selectivity by Crystal Filter
DESCRIPTION
The MAS1017 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. There are only a few
external components needed. The circuit has a
preamplifier, wide range automatic gain control,
demodulator and output comparator built in. The
output signal can be processed directly with an
additional digital circuitry to extract the data from the
received signal.
FEATURES
• Highly Sensitive AM Receiver
• Wide Supply Voltage Range
• Very Low Power Consumption
• Power Down and Power Up Control
• Only a Few External Components Needed
• Wide Frequency Range from 40 kHz to 100 kHz
• High Selectivity by Quartz Crystal Filter
APPLICATIONS
• Time Signal Receiver for DCF77 (Germany)
