DESCRIPTION
The ADS8413 is a 16-bit, 2-MSPS, analog-to-digital (A/D) converter with 4-V internal reference. The device includes a capacitor based SAR A/D converter with inherent sample and hold.
The ADS8413 also includes a 200-Mbps, LVDS, serial interface. This interface is designed to support daisy chaining or cascading of multiple devices. A selectable 16-/8-bit data frame mode enables the use of a single shift register chip (SN65LVDS152) for converting the data to parallel format.
The ADS8413 unipolar differential input range supports a differential input swing of –Vref to +Vref with a common-mode voltage of +Vref/2.
The nap feature provides substantial power saving when used at lower conversion r...
