Note 1: VREF···Reference voltage includes error.
Note 2: Reference Voltage Change is defined as
∆VREF_T [mV] = ± < Reference Voltage Change [ppm/°C] > × <-40°C ∼ 25°C> × VREF
The maximum value of “Reference Voltage Change” is determined based on sampling evaluation from the 5 initial
production lots, and thus not tested in the production test. Therefore, these values are for the reference design
purpose only.
