Conditions (regular specifications):
V_CC = 4.5 V to 5.5 V, PV_CC = 4.5 V to 5.5 V,
AV_CC = 4.5 V to 5.5 V, AV_refh = 4.5 V to AV_CC,
V_SS = PLLV_SS = AV_SS = AV_refh = 0 V,
T_a = –40°C to +85°C
Conditions (wide-range specifications): V_CC = 3.0 V to 3.6 V, PV_CC = 4.5 V to 5.5 V,

Notes: 1. Conversion time per channel when the sample-and-hold circuit is not used and the A/D
clock operates at 40 MHz.
2. Conversion time per channel when the sample-and-hold circuit is not used and the A/D
clock operates at 32 MHz.
3. Non-linear error is a reference value.
4. Guaranteed range from AV_refl + 0.25 V to AV_refh – 0.25 V.
