5. Electrical Characteristics
Table 5.10 DC Characteristics (8)
Conditions: VCC = 2.7 V to 5.5 V, AVCC0 = VREFH0 = VCC to 5.5 V, VSS = AVSS0 = VREFL0 = 0 V, Ta = â40 to +105°C
The ripple voltage must meet the allowable ripple frequency fr (VCC) within the range between the VCC upper limit (5.5 V) and
lower limit (2.7 V). When VCC change exceeds VCC ±10%, the allowable voltage change rising/falling gradient dt/dVCC must be
met.
