1 EVM Overview

1.1 Features

ADS7263/8363EVM Features:

• Full-featured evaluation board for the ADS7263 and ADS8363, dual, 1-MSPS, 14-/16-bit, serial output,

4x2 or 2x2 analog input, simultaneous sampling ADCs

• Analog inputs can be configured as single-ended or differential

• Onboard reference

• High-speed serial interface

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with

the ADS7263/8363EVM. Unless otherwise noted, the term ADS7263/8363 refers to the operation of either

the ADS7263 or the ADS8363 converter.

1.2 Introduction

The ADS7263 and ADS8363 are high-speed, low-power, 14- and 16-bit ADCs that operate from

independent +5-V AV

and DV

supplies.

The four, fully-differential analog inputs are divided into two pairs (A and B). The ADS7263 and ADS8363

each accept an analog input voltage in the range of –VREF to +VREF (5 V

), centered on the internal

+2.5-V (typical) reference. The part also accepts bipolar input ranges when a level shift circuit is used in

the analog front-end circuitry. Refer to Section 12 of the design guide, Op Amps for Everyone (SLOD006;

available for download at www.ti.com) for further information on various circuit applications.
