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.

It is available in 10-pin MSOP and SON packages.
