DESCRIPTION

The ADS8517 is a complete low-power, single 5-V

supply, 16-bit sampling analog-to-digital (A/D)

converter.

capacitor-based, successive approximation register

(SAR) A/D converter with sample-and-hold, clock,

reference, and data interface. The converter can be

configured for a variety of input ranges including ±10

V, 4 V, and 5 V. For most input ranges, the input

voltage can swing to 25 V or –25 V without damage

to the device.

SPI™-Compatible Serial Output With

Daisy-Chain (TAG), SPI Master/Slave Feature

contains

complete,

16-bit,

•

Full Parallel Interface

Binary Twos Complement or Straight Binary

Output Code Formats

•

Single 4.5-V to 5.5-V Analog Supply, 1.65-V to

5.5-V Interface Supply

•

Uses Internal 2.5-V or External Reference

No External Precision Resistors Required

Low Power Dissipation (ADC+REF+BUF):

An SPI-compatible serial interface allows data to be

synchronized to an internal or external clock. A full

parallel interface using the selectable BYTE pin is

also provided to allow the maximum system design

flexibility. The ADS8517 is specified at a 200-kHz

sampling rate over the industrial –40°C to +85°C

temperature range.
