description: |
  The ADS7128 and ADS7138 chips are 12-bit, 8 channel analog-to-digital
  converters (ADC) with build-in digital window comparator (DWC), using the
  I2C interface.
  ADS7128 differs in the addition of further hardware features, like a
  root-mean-square (RMS) and a zero-crossing-detect (ZCD) module.
