     13  The ADS131E0x are a family of multichannel, simultaneous sampling,
     14  24-bit, delta-sigma, analog-to-digital converters (ADCs) with a
     15  built-in programmable gain amplifier (PGA), internal reference
     16  and an onboard oscillator.
     17  The communication with ADC chip is via the SPI bus (mode 1).
