Ultra-Low-Power, Octal, 12-Bit, 50Msps,
1.8V ADC with Serial LVDS Outputs
Typical Operating Characteristics (continued)
(VAVDD = 1.8V, VOVDD = 1.8V, internal reference, AIN = -0.5dBFS, differential clock, VCLKD = 1.5VP-P, fCLK = 50MHz, programmable
registers at default settings (Table 1), TA = -40NC to +85NC, typical values are at TA = +25NC, unless otherwise noted. Specifications
are 100% production tested at TA R +25NC. Specifications for TA < +25NC are guaranteed by design and characterization.)
