Unique Features
CMOS Hall IC Technology
The Chopper Stabilized Amplifier, using
switched capacitor techniques, eliminates the
amplifier offset voltage, which in bipolar devices
is a major source of temperature sensitive drift.
CMOS makes this advanced technique possi-
ble.
The CMOS chip is also much smaller than the
Bipolar chip, allowing very sophisticated cir-
cuitry to be placed in less space. The small chip
size also contributes to lower physical stress
and less power consumption.
Installation
Consider temperature coefficients of Hall IC and
magnetics, as well as air gap and life time varia-
tions. Observe temperature limits during wave
soldering.
Application Comments
If reverse supply protection is desired, use a re-
sistor in series with the V
DD
pin. The resistor will
limit the Supply Current (Fault), I
DD
, to 50mA.
For severe EMC conditions, use the application
circuit below.
