40Msps, 12-Bit ADC
Typical Operating Characteristics (continued)
(V_DD = 3.3V, OV_DD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), C_REFOUT = 0.1µF, C_L ≈ 5pF at digital outputs, V_IN = -0.5dBFS
differential input, DCE = high, CLKTYP = high, PD = low, G/T = low, f_CLK = 40MHz (50% duty cycle), C_REFP = C_REFN = 0.1µF to GND, 1µF
in parallel with 10µF between REFP and REFN, C_COM = 0.1µF in parallel with 2.2µF to GND, T_A = +25°C, unless otherwise noted.)
