20-Bit Sigma-Delta ADC
The inherent linearity of the ADC is excellent, and endpoint accuracy is ensured by self-calibration of zero and full scale which may be initiated at any time. The self-calibration scheme can also be extended to null system offset and gain errors in the input channel.
The output data is accessed through a serial port, which has two synchronous modes suitable for interfacing to shift registers or the serial ports of industry standard microcontrollers.
CMOS construction ensures low power dissipation, and a power down mode reduces the idle power consumption to only 10µW.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
