Subject: [PATCH 0/2] hwmon: Add TI ads1000/ads1100 driver package
Date: Wed, 15 May 2019 01:58:07 +0300
Message-ID: <20190514225810.12591-1-fancer.lancer@gmail.com> (raw)

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.
