(V_AVDD = +3.0V to +3.6V, V_DVDD = +3.0V, C_DVREG = 10µF, V_AGND = V_DGND = 0V, common-mode input voltage = V_AVDD/2, V_REFBP
= V_REFA = V_REFB = V_REFC = V_REFD = +2.5V (external reference), V_REFDAC = V_REFDACH = +1.25V (external reference), V_REFDACL =
0V, C_REFBP = C_REFA = C_REFB = C_REFC = C_REFD = C_REFDAC = 1µF, f_SCLK = 38.4MHz, f_EXCLK = 38.4MHz (external clock applied to
OSCIN), clock divider set to 4, SHDN = DACSTEP = UP/DWN = DGND, CONVRUN = DVDD, all analog inputs driven directly through
a series 150Ω/330pF anti-alias filter, PGA gain = 1. Default filters and gain settings. DIFF = 1. T_A = T_MIN to T_MAX, unless otherwise noted
(Note 1). Typical values are at T_A = +25°C.)
