Description
Description
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. This application note shows how to use the MCP3551 22-Bit Delta-Sigma ADC PICtail? Demo Board circuitry and DataView® software to quickly evaluate sensor or system performance, as well as how to interface the device to PICmicro® microcontrollers.
