1.8V, 10-Bit, 250Msps Analog-to-Digital Converter
with LVDS Outputs for Wideband Applications
ELECTRICAL CHARACTERISTICS (continued)
(AV_CC = OV_CC = 1.8V, AGND = OGND = 0, f_SAMPLE = 250MHz, differential sine-wave clock input drive, 0.1µF capacitor on REFIO,
internal reference, digital output pins differential R_L = 100Ω ±1%, C_L = 5pF, T_A = T_MIN to T_MAX, unless otherwise noted. ≥25°C guar-
anteed by production test, <25°C guaranteed by design and characterization. Typical values are at T_A = +25°C.)
