Guaranteed Sensitivity Range
The magnetic sensitivity, Sens,
can be programmed around its nominal value, 0.7 to 16 mV/G
depending on device type, within the sensitivity range limits:
Sens(min) and Sens(max). Refer to the Guaranteed Quiescent
Voltage Output Range section for a conceptual explanation of
how value distributions and ranges are related.
Average Sensitivity Step Size
Refer to the Average Quiescent
Voltage Output Step Size section for a conceptual explanation.
Sensitivity Programming Resolution
Refer to the Quiescent
Voltage Output Programming Resolution section for a conceptual
explanation.
Sensitivity Temperature Coefficient
Device sensitivity changes
as temperature changes, with respect to its programmed sensitiv-
ity temperature coefficient, TCSENS. TCSENS is programmed at
150°C, and calculated relative to the nominal sensitivity program-
ming temperature of 25°C. TCSENS (%/°C) is defined as:
Sens
T2 – SensT1
Sens
T1
T2–T1
1
TC
Sens =
×100%
,
(6)
where T1 is the nominal Sens programming temperature of 25°C,
and T2 is the TCSENS programming temperature of 150°C. The
ideal value of Sens over the full ambient temperature range,
SensEXPECTED(TA), is defined as:
Sens
T1 [1 + TCSENS (TA –T1) / 100%]
Sens
EXPECTED(TA) =
(7)
SensEXPECTED(TA) should be calculated using the actual measured
values of SensT1 and TCSENS rather than programming target
values.
Sensitivity Drift Due to Package Hysteresis
Package stress and
relaxation can cause the device sensitivity at TA = 25°C to change
during and after temperature cycling.
For purposes of specification, the sensitivity drift due to package
hysteresis, SensPKG, is defined as:
Sens
(25°C)2 – Sens(25°C)1
Sens
(25°C)1
Sens
PKG =
×100% ,
(8)
where Sens(25°C)1 is the programmed value of sensitiv-
ity at TA = 25°C, and Sens(25°C)2 is the value of sensitivity at
TA = 25°C, after temperature cycling TA up to 150°C, down to
–40°C, and back to up 25°C.
Linearity Sensitivity Error
The 136x family is designed to
provide a linear output in response to a ramping applied magnetic
field. Consider two magnetic fields, B1 and B2. Ideally, the sen-
sitivity of a device is the same for both fields, for a given supply
voltage and temperature. Linearity error is present when there is a
difference between the sensitivities measured at B1 and B2.
Linearity Error is calculated separately for the positive
(LinERRPOS) and negative (LinERRNEG) applied magnetic fields.
Linearity error (%) is measured and defined as:
Sens
BPOS2
Sens
BPOS1
Sens
BNEG2
Sens
BNEG1
1–
Lin
ERRPOS =
×100% ,
1–
Lin
ERRNEG =
×100% ,
(9)
where:
|V
OUT(Bx) – VOUT(Q)|
Bx
Sens
Bx =
,
(10)
and BPOSx and BNEGx are positive and negative magnetic fields,
with respect to the quiescent voltage output such that
|BPOS2| = 2 ×|BPOS1| and |BNEG2| = 2 ×|BNEG1|. Then:
Lin
ERR
max( LinERRPOS , LinERRNEG)
=
.
(11)
Note that unipolar devices only have positive linearity error,
LinERRPOS.
