14-Bit, 95Msps, 3.3V ADC
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.3V, OVDD = 1.8V, GND = 0, REFIN = REFOUT (internal reference), VIN = -0.5dBFS, CLKTYP = high, DCE = high, PD = low,
G/T = low, fCLK = 95MHz (50% duty cycle, 1.4VP-P square wave), TA = -40°C to +85°C, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 1)
