MAS1017

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.
