Designing with the MCP3551 Delta-Sigma ADC

From Microchip Technology, Inc.
 

 
The MCP3551 delta-sigma ADC is a high resolution converter. This application note discusses various design techniques to follow when using this device. Typical application circuits are discussed first, followed by a section on noise analysis. This device has a LSB size that is smaller than the noise voltage, typical of any high-resolution ADC. Due to this, the performance of the device (and system) cannot be analyzed by simply looking at the binary output stream. Collecting data and visually analyzing the result is required; when designing circuits it is important to provide a way to get the data points to a PC.
