An Arduino library for MCP3903 A/D converter


Kerry Wong writes:

MCP3903 is a six channel Delta-Sigma A/D converter. It features six synchronous sampling differential channels which can be programmed to sample between 16 bit and 24 bit accuracy, the gain for each channel can also be programmatically set from 1 up to 32. It also has an internal low tempco (5ppm/°C) voltage reference, making MCP3903 an excellent choice for digitizing small differential signals from various sensors.

I have created a library for Arduino. It allows you to explore most of the functionalities MCP3903 provides with ease. The library can be downloaded towards the end of this post as usual. And it is also available on GitHub.
