ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = +5V ±5%, AV_SS = -5V ±5%, DV_DD = +5V ±5%, V_REFIN = +2.5V (external reference), AGND = DGND = 0, 4.7µF capacitor
from REFOUT to AGND, 0.1µF capacitor from REFIN to AGND, f_CLK = 16MHz, external clock, 50% duty cycle. T_A = T_MIN to T_MAX,
unless otherwise noted. Typical values are at T_A = +25°C.)
