Description : 1.2-V, 12-/10-/8-BIT, 200-KSPS/100-KSPS, MICRO-POWER, MINIATURE ANALOG-TO-DIGITAL CONVERTER WITH SERIAL INTERFACE View

DESCRIPTION
The ADS7866/67/68 are low power, MINIATURE, 12/10/8-bit A/D CONVERTERs each WITH a unipolar, single-ended input.

The device supports unipolar, true-differential analog input signals WITH a differential input swing of –VREF to +VREF. This true-differential analog input structure allows for a common-mode voltage of any value in the range of 0 V to +VREF (when both inputs are WITHin the operating input range of –0.1 V to VREF + 0.1 V).
Device operation is optimized for very low-power operation. Power consumption directly scales WITH speed. This feature makes the ADS8887 excellent for lower-speed applications.
