MAS1016B
AM Receiver IC
• High Sensitivity
• Very Low Power Consumption
• Wide Supply Voltage Range
• Power Down Control
• Control for AGC On
• High Selectivity by Crystal Filter
DESCRIPTION
The MAS1016B 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. WWVB in USA and JJY in
Japan require use of AGC control procedure, which is
simplified in MAS1016B.

Notes:
1) Pin 5 between quartz crystal filter pins must be connected to VSS to eliminate package leadframe parasitic
capacitances disturbing the crystal filter performance. All other NC (Not Connected) pins are also
recommended to be connected to VSS to minimize noise coupling.
2) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced (modulated)
- the output is a current source/sink with |IOUT| > 5 µA
- at power down the output is high impedance
3) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (working)
- Internal pull-up (to AGC on) with current < 1 µA which is switched off at power down
4) PDN = VSS means receiver on; PDN = VDD means receiver off
