Alwyn DSouza

Part Number: ADS1293

There is no mention of bipolar supplies in the ADS1293 datasheet, is it possible to use this chip with bipolar supplies?

Hi Alwyn,

Unfortunately not. The ADS1293 operates from an Analog Supply Voltage of 2.7 V to 5.5 V and a Digital Supply Voltage of 1.65 V to 3.6 V.

Hi Alwyn,

There's no specific mention of unipolar or bipolar in the datasheet, but VSS and VSSIO are both intended to be tied to ground. The Electrical Characteristics table is specified with VSS = VSSIO = 0 V.
