Anyone got any idea how I might determine the pin diagram of the amplifier APS00A that is designed to be matched to APS00B magnetoresistive sensor. Believe it or not you can a buy the IC and there is no datasheet for it. Honeywell hasn't got back to me yet.
The APS00A is just an optimised dual instrumentation apmlifier for use with the APS00B, as its operable with 5V only its convenient for my sensor project. It is referenced in APS00B sensor datasheet but does not give any hint as to what the pin diagram might be! I tried:
Pin 1 = B+in
Pin 2 = A+in
Pin 3 = One of the outputs A or B
Pin 4 = Vs
Pin 5 = B-in
Pin 6 = A-in
Pin 7 = One of the outputs A or B
Pin 8 = GND
Which is a solid guess as to what it might be as it is the same APS00B but doesn't work!
I also tried rotating 180deg with the above pin/locations.
Does anyone know how I could deduce the any of the pins of an instrumentation amplifier like this?
