GENERAL DESCRIPTION
The EVAL-AD4858FMCZ is designed to demonstrate the perform-
ance of the AD4858 and provide access to many included configu-
ration options that are accessed via an easy to use ACE plug-in
graphical interface. The AD4858 is a fully buffered, 8-channel simul-
taneous sampling, 20-bit, 1 MSPS data acquisition system (DAS)
with differential, wide common mode range inputs.
The EVAL-AD4858FMCZ on-board components include also the
following:
The
LTC6655
high precision, low drift, 4.096 V voltage reference
►
(not used by default)
The LT1761, low noise, 1.8 V, 2.5 V, and 5 V low dropouts
►
(LDOs)
The
LT8330
low quiescent current (I
