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.
