V
CLP
voltages are production-tested, with the sole exception of the A1360 V
CLP(HIGH)
, which is guaranteed by design (the low sensitivity and corresponding high
gauss levels required for testing A1360 V
CLP(HIGH)
make production testing impractical).
4
Noise is dependent on the sensitivity of the device and the filter capacitance. An 8 mV peak-to-peak noise floor exists that is independent of device sensitivity. This noise
floor attenuates proportionate to the filter capacitance (and device bandwidth).
5
Unit of measure (phase degrees) in reference to the magnetic input signal.
6
High-to-low transition of output voltage is a function of external load components and device sensitivity.

typically starts below the lower clamp voltage, V

Sens guaranteed by design.

Linearity is only guaranteed for output voltage ranges of ? V from the quiescent output for bidirectional devices and +2 V from the quiescent output for unidirectional
devices. These linearity ranges are only valid within the operating output range of the device. The operating output range is confined to the region between the output clamps.
Linearity may shift by up to +/- 1 % over the lifetime of this product.
19
Symmetry error is only valid for bidirectional devices. Symmetry may shift by up to ?% over the lifetime of this product.
