_______________Detailed Desc ription
The MAX1114 is a 150Msps, monolithic, 8-bit parallel
flash analog-to-digital converter (ADC) with an analog
bandwidth of over 200MHz. A major advance over pre-
vious flash converters is the inclusion of 256 input pre-
amplifiers between the reference ladder and input
comparators. (See Functional Diagram.) This feature
not only reduces clock-transient kickback to the input
and reference ladder due to a low AC beta, but also
reduces the effect of the dynamic state of the input sig-
nal on the latching characteristics of the input compara-
tors. The preamplifiers act as buffers and stabilize the
input capacitance so it remains constant for varying
input voltages and frequencies, making the part easier
to drive than previous flash converters. The MAX1114
incorporates a special decoding scheme that reduces
metastable errors (sparkle codes or flyers) to a maxi-
mum of 1LSB.
