TYPICAL APPLICATIONS
Magnetic tape scanning (field movement measurement
for magnetic tape ruler):
The changing voltage peaks in both AMR bridges are
used for the tape movement measurement.
ZMX40M plus two instrumentation amplifiers for magnetic tape ruler
Current sensor (by combining both bridge outputs and a high isolation voltage)
This double chip solution with the current loop conductor
guarantees good rejection of external fields and a high
isolation voltage.
