DEMO MANUAL DC2183A

Quick start proceDure

DC2183 is easy to set up to evaluate the performance 

of  the  LTC2107  A/D  converter.  Refer  to  Figure 1 for 

proper measurement equipment set-up and follow the 

procedure below: 

Setup

The DC1371 Data Acquisition and Collection System was 

supplied with the DC2183 board. Follow the DC1371 Quick 

Start Guide to install the required software and for con-

necting the DC1371 to the DC2183 and to a PC.
