Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(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.)
