where BPOS and BNEG are two magnetic fields with opposite

Guaranteed Sensitivity Range The magnetic sensitivity, Sens, 
can be programmed around its nominal value within the sensitiv-
ity range limits: Sens(min) and Sens(max). Refer to the Guaran-
teed Quiescent Duty Cycle Output Range section for a conceptual
explanation of how value distributions and ranges are related.
Average Sensitivity Step Size Refer to the Average Quiescent 
Duty Cycle Output Step Size section for a conceptual explana-
tion.
Sensitivity Programming Resolution Refer to the Quiescent 
Duty Cycle Output Programming Resolution section for a con-
ceptual explanation.
Carrier Frequency Programming Range The PWM output sig-
nal carrier frequency, f
PWM
 ,can be programmed around its nomi-
nal value within the carrier frequency range limits, f
PWM
(min)
and f
PWM
(max). Refer to the Guaranteed Quiescent Duty Cycle
Output Range section for a conceptual explanation of how value
distributions and ranges are related.
Average Carrier Frequency Step Size Refer to the Average 
Quiescent Duty Cycle Output Step Size section for a conceptual
explanation.
Carrier Frequency Programming Resolution Refer to the Qui-
escent Duty Cycle 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, TC
SENS
. TC
SENS
 is programmed at
125癈, and calculated relative to the nominal sensitivity program-
ming temperature of 25癈. TC

where T1 is the nominal Sens programming temperature of 25癈,
and T2 is the TC

 programming temperature of 125癈. The
ideal value of Sens over the full ambient temperature range,

Sens
EXPECTED(TA)

values of Sens
T1

Sensitivity Drift Through Temperature Range Second order 
sensitivity temperature coefficient effects cause the magnetic sen-
sitivity, Sens, to drift from its expected value over the operating
ambient temperature range, T
A
. For purposes of specification, the
sensitivity drift through temperature range, Sens
TC

as:

Sensitivity Drift Due to Package Hysteresis Package stress and 
relaxation can cause the device sensitivity at T
A
 = 25癈 to change
during and after temperature cycling.
For purposes of specification, the sensitivity drift due to package
hysteresis, Sens
PKG
, is defined as:
 
Sens
(25癈)2
 Sens
(25癈)1
Sens

where Sens
(25癈)1
 is the programmed value of sensitiv-
ity at T
A
 = 25癈, and Sens
(25癈)2
 is the value of sensitivity at
T
A
 = 25癈, after temperature cycling T
A
 up to 125癈, down to
40癈, and back to up 25癈.
Linearity Sensitivity Error The 1351 is designed to provide a 
linear output in response to a ramping applied magnetic field.
Consider two magnetic fields, B1 and B2. Ideally, the sensitivity
of a device is the same for both fields, for a given supply voltage
and temperature. Linearity error is present when there is a differ-
ence between the sensitivities measured at B1 and B2.
Linearity Error is calculated separately for the positive
(Lin
ERRPOS
) and negative (Lin
ERRNEG
) applied magnetic fields.
Linearity error (%) is measured and defined as:
 
Sens

BPOS1
