The same analysis was given to a 0.060" wide trace of the same thickness. A voltage of 8.33V was
applied and the resulting graph is shown below.
The current in this trace was swept from zero to nine Amps, similarly to the 90-mil analysis. The
sensor output to current correlation from this graph is 4.0 ± 0.1 mV/V/A. The differences between the
90 and 60-mil traces is due to the field distribution/density differences between the two due to the
difference in width.
Resolution
The resolution of the sensor is a function of environmental electromagnetic noise, intrinsic noise, and
hysteresis. In most applications, the environmental noise is the limiting factor in resolution. Data and
information in this section are based upon non-filtered, non-amplified, non-shielded output. In this
“raw” configuration, a resolution of better than 1 mA was found. With proper filtering, amplifying and
shielding, the noise level can be decreased and thus the usable resolution will increase.
Hysteresis and Repeatability in GMR Current Sensors
All magnetic materials have an effect called magnetic hysteresis. This hysteresis contributes greatly to
the error values given above. Hysteresis also creates a potential that the same current can produce two
different voltage outputs. The hysteresis, and thus the error, is largest when the current changes
direction. If the current changes direction, the precision of the output at low currents decreases
significantly. The specified error of 0.7% will not be obtained again until the current goes above
approximately 2A. This guideline is very rough as applications vary.
