Description

General part information

ADS8319 Series

The ADS8319 device is a 16-bit, 500-kSPS, analog-to-digital converter (ADC) that operates with a 2.25-V to 5.5-V external reference. The device includes a capacitor-based, successive-approximation register (SAR) ADC with inherent sample and hold.

The device includes a 50-MHz, SPI-compatible serial interface. The interface is designed to support daisy-chaining or cascading of multiple devices. Furthermore, aBusy Indicatormakes synchronizing with the digital host easy.

The device unipolar, single-ended input range supports an input swing of 0 V to +VREF.
