ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD = +5V, V_DVDD = +3V, V_AGND = V_DGND = 0V, V_REF = V_REFMS = +2.5V (external reference), C_REF = C_REFMS = 0.1µF, C_REF+ =
C_REF- = 0.1µF, C_REF+-to-REF- = 2.2µF || 0.1µF, C_COM = 2.2µF || 0.1µF, C_MSV = 2.2µF || 0.1µF (unipolar devices), MSV = AGND (bipo-
lar devices), f_CLK = 16.67MHz 50% duty cycle, INTCLK/EXTCLK = AGND (external clock), SHDN = DGND, T_A = T_MIN to T_MAX,
unless otherwise noted. Typical values are at T_A = +25°C. See Figures 3 and 4.)
