signal-to-noise ratio (SNR) specifications will degrade.
The MAX105
’
s on-board, wide-bandwidth input ampli-
fiers (I&Q) reduce this effect significantly, allowing pre-
cise digitizing of fast analog data at high conversion
rates. The input amplifiers buffer the input signal and
allow a full-scale signal input range of ±400mV
(800mV
p-p
).
Internal Reference
The MAX105 features an integrated, buffered +2.5V
precision bandgap reference. This reference is internal-
ly scaled to match the analog input range specification
of ±400mV. The data converter
’
s reference output
(REF) can source up to 500μA. REF should be buffered,
if used to supply external devices.
LVDS Digital Outputs
The MAX105 provides data in two
’
s complement format
to differential LVDS outputs. A simplified circuit
schematic of the LVDS output cells is shown in
Figure
