MAS1016

AM Receiver IC

•Wide Supply Voltage Range

•Power Down and Power Up Control

•Control for AGC On

DESCRIPTION

The MAS1016 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.
