MAS6180B

AM Receiver IC

• Single Band Receiver IC

• High Sensitivity

• Very Low Power Consumption

• Wide Supply Voltage Range

• Power Down Control

• Control for AGC On

• High Selectivity by Crystal Filter

• Fast Startup Feature

DESCRIPTION

The MAS6180 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.

MAS6180 has two options for compensating shunt

capacitances

of

different

crystals

(See

ordering

information on page 14).
