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 rates.

The ADS8413 is available in a 48-pin QFN package.
