1.8V, Low-Power, 12-Bit, 250Msps
ADC for Broadband Applications
ELECTRICAL CHARACTERISTICS (continued)
(AVCC = OVCC = 1.8V, AGND = OGND = 0, fSAMPLE = 250MHz, differential clock input drive, 0.1µF capacitor on REFIO, internal ref-
erence, digital output pins differential RL = 100â¦. Limits are for TA = -40°C to +85°C, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 1)
