ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = DV_DD = +5.0V, DRV_DD = +3.0V, AGND = DGND = DRGND = 0, INTCLK/EXTCLK = AGND, f_CLK = 5MHz, input range =
±10V, REFP2 = REFP1, REFN2 = REFN1, COM1 = COM2, 1.0nF from REFADC to AGND, 1.0µF and 0.1µF from COM1 to AGND,
0.1µF from REFP1 to AGND, 0.1µF from REFN1 to AGND, 1.0µF from REFP1 to REFN1. Typical values are at T_A = +25°C. T_A = T_MIN
to T_MAX, unless otherwise noted.)
