This a simple single-channel ADC device similar to ads1100 series, but with much less capabilities. These ADCs are working over i2c-interface with just one differential input and with configurable 12-16 bits resolution. Sample rate is fixed to 128 for ads1000 and can vary from 8 to 128 for ads1100. Vdd value reference value must be supplied so to properly translate the sampled code to the real voltage. Even though ads1000/ads1100 devices seem more like ads1015 series, they in fact pretty much different. First of all ads1000/ads1100 got less capabilities: just one port, no configurations of digital comparator, no input multi-channel multiplexer, smaller PGA and data-rate ranges. In addition they haven't got internal voltage reference, but instead are created to use Vdd pin voltage. Finally the output code value is provided in different format. As a result it was much easier for development and for future support to create a separate driver, which is opensoureced by means of this patchset.
