Manufacturer Part Number
MAS9178A1TB00.01
Description
AM Receiver IC

Datasheet
DESCRIPTION
The MAS9178 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. Unlike MAS1016A and
