EVAL-AD4115SDZ

GENERAL DESCRIPTION

The EVAL-AD4115SDZ is a full featured evaluation board that
can evaluate all features of the AD4115. The
125 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-AD4115SDZ 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-AD4115SDZ
from the PC USB port.
The
AD411x Eval+
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
data sheet, which must be consulted in conjunction with this
user guide when working with the EVAL-AD4115SDZ.
