1 Although the device is accurate over the entire linear range, the device is programmed for maximum accuracy over the range defined by I POA .
The reason for this is that in many applications, such as motor control, the start-up current of the motor is approximately three times higher than the
running current.
2 V pk-pk noise (6 sigma noise) is equal to 6 × V NOISE(rms) . Lower noise levels than this can be achieved by using C f for applications requiring narrower
bandwidth. See Characteristic Performance page for graphs of noise versus C f and bandwidth versus C f .
3 This parameter can drift by as much as 2.4% over the lifetime of this product.
4 This parameter can drift by as much as 13 mV over the lifetime of this product.
5 This parameter can drift by as much as 2.5% over the lifetime of this product.
