ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD1 = V_AVDD2 = V_DVDD = V_DVDD0 = 5V, V_AGND1 = V_DGND = V_DGNDO = V_AGND2 = V_AGND3 = 0V, f_CLK = 3.5MHz (50% duty
cycle), external clock mode, V_REF = 4.096V (external reference operation), REFCAP = AVDD1, maximum single-ended bipolar input
range (±3 x V_REF), C_DOUT = 50pF, C_SSTRB = 50pF, T_A = -40°C to +85°C, unless otherwise noted. Typical values are at T_A = +25°C.)
