16-BIT, 500-KSPS, SERIAL INTERFACE MICROPOWER, MINIATURE,

SAR ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

•

500-kHz Sample Rate

The ADS8318 is a 16-bit, 500-KSPS analog-to-digital

converter. It operates with a 2.048-V to 5.5-V external

reference. The device includes a capacitor based,

SAR A/D converter with inherent sample and hold.

16-Bit Resolution

Zero Latency at Full Speed

Unipolar, Differential Input, Range: –V_refto V_ref

The devices includes a 50-MHz SPI compatible serial

interface. The interface is designed to support daisy

chaining or cascading of multiple devices. Also a

Busy Indicator makes it easy to synchronize with the

digital host.

SPI Compatible Serial Interface with Daisy

Chain Option

•

Excellent Performance:

–

95.2dB SNR Typ at 10-kHz I/P

–108dB THD Typ at 10-kHz I/P

±1.0 LSB Max INL

The ADS8318 unipolar differential input range

supports a differential input swing of –V_refto +V_refwith

a common-mode of +V_ref/2.

±0.75 LSB Max DNL

Device operation is optimized for very low power

operation, and the power consumption directly scales

with speed. This feature makes it attractive for lower

speed applications.
