ADS8318,pdf (Serial Interface

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 -V_ref to +V_ref with a common-mode of +V_ref/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.
