The electronics industry has been w
the environmental impact of the use of lead (Pb) in solder finishes. Increasing customer demand and
directives to decrease the amounts of lead in consumer electronics products from governments around
the globe, drives this effort.
Lead-free finishes u tilizing p
of our products. However, additional lead times are associated with these parts.
Since most lead-free solders being used in board assembly environments
temperatures than traditional tin-lead solders, higher reflow temperatures may be necessary to form an
equivalent solder joint between the component and the PC board. NVE characterizes all lead-free
packages using elevated temperature (245°C to 260°C) reflow profiles characteristic of lead-free board
assembly environments. All lead-free products will be identified with an “E” suffix on the part number
and a lower case “e” marking on the package.
This lead-free transition is an important comp
protecting the environment and our responsibility to our customers and the communities around the
world in which we do business. We remain dedicated to meeting our customers’ requirements and
expectations.

Recommended Solder Reflow Profile
NVE recommends the following soldering profile:
300
For leaded (Pb) parts, the peak temperature shown in this profile can be decreased to as low as 230°C.
Exceeding 265°C at peak or the time at peak temperature shown in this profile can damage the parts.
Specifically:
1. AA- and AD-Series sensors are rated at 150°C maximum storage temperature. They can withstand
the solder profile shown above with no harmful effects. However, temperatures above 265°C for
even a brief period or extended periods above 160°C can cause degradation of the GMR sensor
element.
2. AKL- and DD-Series parts contain an on-chip EEPROM. Exposure to temperatures in excess of
265°C can cause EEPROM data corruption, which will cause the parts to fall out of specification.

Electrical Offset: The inherent imbalance of the bridge expressed in differential voltage output.
RBP: Reverse Battery Protection.
Definitions and Conversion Factors
Definitions:
CSK or Sink: Current sinking output, also referred to as Open Collector output.
Differential: The field difference between the Operate Point and the Release Point.
HBM: Human Body Model for ESD specifications.
Hysteresis: The maximum deviation in volts between the output with increasing field and the output
with decreasing field, where the applied field is unipolar (applied in either a positive or negative
direction, without crossing the zero field point), divided by Voltage Span. Expressed as a percentage.
Input Voltage Range: The voltage range that can be applied across the bridge.
IOL (Current Output Low): The output current in the low (logic 0) state (output stage switched on).
Max Output: A specification given in millivolts per applied voltage. This is the maximum output
voltage possible. This output condition is achieved when one set of resistors is in magnetic saturation
(have achieved the maximum resistance change possible) while the other pair are at zero applied
magnetic field.
Nonlinearity: The maximum deviation from a linear fit taken over the Field Range divided by the
Voltage Span. Expressed as a percentage.
Off-axis Characteristic: A specification that describes the variation in sensor output versus the angle
between the applied field direction and the sensitive axis of the GMR sensor with constant electrical
and magnetic inputs applied. Applicable to non-integrated bridge sensors. The output will vary as the
cosine of the angle rotated.
Operate Point: The field level which produces a logical change in state from “0” to “1” in NVE’s
digital magnetic field sensors ADXXX-XX.
Operating Frequency: Frequency range within which a sensor will produce a responsive output.
Output Leakage Current (Current Output High): The output current in the high (logic 1) state
(output stage switched off).
Output Saturation Voltage (Voltage Output Low): The output voltage in the low (logic 0) state
(output stage switched on).
Release Point: The field level which produces a logical change in state from “1” to “0” in NVE’s
digital magnetic field sensors ADXXX-XX.
Resistor Separation: This is the mean separatio n b etween the tw o p airs of resistors, in a Gr adio meter
or Differential sensor.
Sensitivity: A measure of the output magnitude based on electrical and magnetic input conditions.
Expressed in millivolts of differential output per applied voltage per Oersted.

Specified Linear Range: Typically 70% of the field it takes to saturate the part. Field dependent
specifications are based upon this range.
TCOI (Temperature Coefficient of Output at Constant Input Current): The variation of the
output voltage over temperature with a constant input current applied. Expressed as a percentage per
unit temperature change.
TCOV (Temperature Coefficient of Output at Constant Input Voltage): The variation of the
output voltage over temperature with a constant input voltage applied. Expressed as a percentage per
unit temperature change.
TCR (Temperature Coefficient of Resistance): The variation of the GMR resistors over
temperature. Expressed as a percentage per unit temperature change.
Voltage Span: The differential output voltage taken from zero to 70% of the saturation field level.
