EVAL-AD4114SDZ
GENERAL DESCRIPTION
The EVAL-AD4114SDZ is a full featured evaluation board that
can evaluate all the features of the AD4114. The
24-bit, 31.25 kSPS, Σ-Δ analog-to-digital converter (ADC) with
a ±10 V input voltage range (16 single-ended channels or eight
fully differential channels). All channels have on-board
overvoltage and overcurrent protection.
The EVAL-AD4114SDZ includes voltage references and power
and data insulation and can be connected to the Analog Devices,
Inc., system demonstration platform (SDP) hardware. The
board provides connection to a PC via a universal serial bus
(USB) port and can provide power for the EVAL-AD4114SDZ
from the PC USB port.
The
AD411x Eval+
evaluation software configures the
functionality and provides dc time domain analysis in the form
of waveform graphs, histograms, and associated noise analysis
for ADC performance evaluation.
Full specifications for the
AD4114
data sheet, which must be consulted in conjunction with this
user guide when working with the EVAL-AD4114SDZ.
