1 Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions, such as T
may vary for individual units, within the specified maximum and minimum limits.
2 Voltage applied to the VREF pin. Note that the V
voltages of less than 2.5 V.
3 If the VREF pin is tied to the VCC pin, the supply current would be I
