• Manufacturer Part Number: MAS9081A1TC00
• Description: Dual Band Receiver IC High Sensitivity
• Manufacturer: MAS [Micro Analog systems]

MAS9081 SAMPLES IN SBDIL 20 PACKAGE
A = Analog, D = Digital, P = Power, G = Ground, I = Input, O = Output, NC = Not Connected
Notes:
1) Pins 5 and 6 between QO and QI must be connected to VSS to eliminate DIL package leadframe parasitic
2) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced
3) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (working)
4) Receiver inputs RFIP and RFIM have both 600 kΩ biasing MOSFET-transistors towards ground
PIN DESCRIPTION
capacitances disturbing the crystal filter performance. All other NC (Not Connected) pins are also
recommended to be connected to VSS to minimize noise coupling.

the output is a current source/sink with |I
at power down the output is pulled to VSS (pull down switch)
Internal pull-up with current < 1 µA which is switched off at power down
