ADS7868 说明

The ADS7866/67/68 are low power, miniature, 12/10/8-bit A/D converters each with a unipolar, single-ended input. These devices can operate from a single 1.6 V to 3.6 V supply with a 200-KSPS throughput for ADS7866. In addition, these devices can maintain at least a 100-KSPS throughput with a supply as low as 1.2 V.

The sampling, conversion, and activation of digital output SDO are initiated on the falling edge of CS\. The serial clock SCLK is used for controlling the conversion rate and shifting data out of the converter. Furthermore, SCLK provides a mechanism to allow digital host processors to synchronize with the con- verter. These converters interface with micro-processors or DSPs through a high-speed SPI compatible serial interface.
