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.

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.

The ADS8318 unipolar differential input range supports a differential input swing of -Vref to +Vref with a common-mode of +Vref/2.

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.
