1. Although the device is accurate over the entire linear range, the device is programmed for maximum accuracy over the
range defined by IPOA .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. Vpk-pk noise (6 sigma noise) is equal to 6 × VNOISE(rms). Lower noise levels than this can be achieved by using Cf for
applications requiring narrower bandwidth. See Characteristic Performance page for graphs of noise versus Cf and
bandwidth versus Cf.
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.
