    Here are the key differences between these devices:

    ADS1281 - This was the first ADC in ADS128x product family.

    ADS1282 - Integrated a PGA & MUX in front of the delta-sigma modulator.

    ADS1283 - Changed to a smaller package, reduced device's power consumption, added an internal offset to move idle tone, and added a /CS pin.

    ADS1284 - Added an optional reduced power mode (from 18 mW to 12 mW). SNR in the low-power mode is reduced by 3 dB.
