Figure 1. DC1762 Setup
Demonstration circuit 1762A is easy to set up to evaluate
the performance of the LTC2165 A/D converter family. Refer
to Figure 1 for proper measurement equipment setup and
follow the procedure below:
Setup
If a DC890 USB demonstration circuit was supplied with
the DC1762A demonstration circuit, follow the DC890
Quick Start Guide to install the required software and for
connecting the DC890 to the DC1762A and to a PC.
