1 See Characteristic Definitions section.
2 fC varies up to approximately ±20% over the full operating ambient temperature range, TA, and process.
3 VCLP voltages are production-tested, with the sole exception of the A1360 VCLP(HIGH), which is guaranteed by design (the low sensitivity and corresponding high
gauss levels required for testing A1360 VCLP(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.
7 Raw device characteristic values before any programming.
8 VOUT(Q)UNIinit typically starts below the lower clamp voltage, VCLP(LOW). When programming the fine quiescent duty cycle for this parameter, several codes may need to be
addressed before VOUT(Q)UNI can be measured above VCLP(LOW).
9 Bits for selecting between VOUT(Q)UNI and VOUT(Q)BI programming ranges.
10 VOUT(Q) guaranteed by design.
11 VOUT(Q)(max) is the value available with all programming fuses blown (maximum programming code set). The VOUT(Q) range is the total range from VOUT(Q)init up to and
including VOUT(Q)(max). See Characteristic Definitions section. Quiescent Voltage Output may drift by an additional ±10 mV over the lifetime of this product.
12 Step size is larger than required, in order to provide for manufacturing spread. See Characteristic Definitions section.
13 Non-ideal behavior in the programming DAC can cause the step size at each significant bit rollover code to be greater than twice the maximum specified value of
StepVOUT(Q) or StepSENS.
14 Overall programming value accuracy. See Characteristic Definitions section.
15 Sens guaranteed by design.
16 Sens(max) is the value available with all programming fuses blown (maximum programming code set). Sens range is the total range from Sensinit up to and including
Sens(max). See Characteristic Definitions section. Sensitivity may drift by an additional ±2% over the lifetime of this product.
17 Programmed at 150°C and calculated relative to 25°C.
18 Linearity is only guaranteed for output voltage ranges of ±2 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 ±1% over the lifetime of this product.
20 Percent change from actual value at VCC = 5 V, for a given temperature, over the guaranteed supply voltage operating range.
21 Percent change from actual value at VCC = 5 V, TA = 25°C, over the guaranteed supply voltage operating range.
OPERATING CHARACTERISTICS (continued)
valid over full operating temperature range, TA; CBYPASS = 0.1 μF, VCC = 5 V, unless otherwise specified
