14-Bit, 95Msps, 3.3V ADC
Typical Operating Characteristics (continued)
(V_DD = 3.3V, OV_DD = 1.8V, GND = 0, REFIN = REFOUT (internal reference), V_IN = -0.5dBFS, CLKTYP = high, DCE = high, PD = low,
G/T = low, f_CLK ≈ 95MHz (50% duty cycle, 1.4V_P-P square wave), T_A = +25°C, unless otherwise noted.)
