Texas Instruments ADS8319 Precision 16-Bit SAR Analog-to-Digital Converter (ADC) is a 500-KSPS analog-to-digital converter that operates with a 2.25V to 5.5V external reference. The device includes a capacitor-based, SAR A/D converter with an 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. Also, a Busy Indicator makes it easy to synchronize with the digital host. The ADS8319 unipolar single-ended input range supports an input swing of 0V to +Vref. 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.
