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.
FEATURES APPLICATIONS
• Wide Supply Voltage Range
• Power Down Control
• Only a Few External Components Needed
• Highly Sensitive AM Receiver
• Control for AGC On
• Time Signal Receiver designed for MSF (British),
WWVB (USA), JG2AS (Japan) and DCF77
(Germany)

Notes:
1) Level = VSS means receiver on; VDD = receiver off
2) Level = VSS means AGC hold; VDD = AGC on (working)
-Internal pull-up with current < 1 µA which is switched off in power down
-During AGC hold the receiver output OUT is hold down to VSS
3) 100% AM results in Level = VSS; 25% AM results in Level = VDD
- the output is a current source/sink with |IOUT| > 5 µA
- at power down the output is tri-state

Notes:
1) Level = VSS means receiver on; VDD = receiver off
2) Level = VDD means receiver on; VSS = receiver off (PDN = VDD)
Internal pull-down resistor > 1MOhm to VSS
3) 100 % AM results in Level = VSS; 25 % AM results in Level = VDD
- the output is a current source/sink with [lout] >5 µA
- at power down the output is tri-state
