Demonstration Circuit 745 Quick Start Guide for LTC2433-1 16-Bit Differential Input Delta Sigma ADC
Quick start guide for the DC745 evaluation board featuring the LTC2433-1 16-bit differential ADC, including hardware setup, jumper settings, and performance testing.
Overview
The DC745 demonstration circuit provides a platform for evaluating the LTC2433-1, a high-performance 16-bit Delta-Sigma analog-to-digital converter. This guide details how to interface the board with the DC590 USB Serial Controller and QuickEval software for data logging and performance measurement. Key hardware features include adjustable jumper settings for reference voltage sources (using the onboard LT1236), trigger modes, and notch frequency selection for 50Hz/60Hz rejection. The document also includes experimental procedures for testing input noise, common mode rejection, bipolar symmetry, and normal mode rejection using external references like the LT1790 series.
Use Cases
- ADC performance verification
- Precision sensor data acquisition evaluation
- Industrial instrumentation prototyping
- Analog-to-digital interface development
