Version

2.0.2

Date: 27 Sep 2016

Source Code Repository:: https://github.com/4-20ma/i2c_adc_ads7828

Programming Style Guidelines:: http://geosoft.no/development/cppstyle.html

Features: The ADS7828 is a single-supply, low-power, 12-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The Analog-to-Digital (A/D) converter features a sample-and-hold amplifier and internal, asynchronous clock. The combination of an I2C serial, 2-wire interface and micropower consumption makes the ADS7828 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS7828 is available in a TSSOP-16 package.
