GENERAL DESCRIPTION
The EVAL-AD4857FMCZ is designed to demonstrate the perform-
ance of the AD4857 and to provide access to many included
configuration options that are accessed via a simple ACE plug-in
graphical user interface (GUI). The AD4857 is a fully buffered,
8-channel simultaneous sampling, 16-bit, 1 MSPS data acquisition
system (DAS) with differential, wide common-mode range inputs.
The EVAL-AD4857FMCZ on-board components include the follow-
ing:
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 dropout (LDO)
►
regulators
The
LT8330
low quiescent current (I
►
For full details on the AD4857, see the AD4857 data sheet, which
must be consulted in conjunction with this user guide when using
the EVAL-AD4857FMCZ evaluation board.
This evaluation board can also be used to evaluate the perform-
ance of the AD4855.
