This document is about the quick start guide for demonstration circuit 745 16-bit differential input delta sigma ADC
This guide explains how to set up and use the DC745 demonstration circuit board to evaluate the LTC2433-1 16-bit differential input delta sigma ADC. It includes hardware setup instructions, connection to the DC590 USB Serial Controller, and basic experiments to demonstrate input noise, common mode rejection, and bipolar symmetry. The board is designed for easy prototyping and direct connection to target applications.
| ADC Resolution | 16-bit |
|---|---|
| Linearity | 0.12 LSB |
| Full-Scale Accuracy | 0.16 LSB |
| Input Noise | 1.45mV RMS |
| Common Mode Rejection | 140 dB |
Connect DC745 to a DC590 USB Serial Controller using the supplied 14-conductor ribbon cable, then connect the DC590 to the host PC with a standard USB A/B cable.
The default reference voltage source is 5.00 volts from the onboard LT1236 reference.
The maximum trigger frequency is 5Hz when Fo is grounded.
