ADS825 说明

The ADS822 and ADS825 are pipeline, CMOS Analog-to-Digital Converters (ADC) that operate from a single +5V power supply. These converters provide excellent performance with a single-ended input and can be operated with a differential input for added spurious performance. These high-performance converters include a 10-bit quantizer, high-bandwidth track-and-hold, and a high-accuracy internal reference. They also allow for the user to disable the internal reference and utilize external references. This external reference option provides excellent gain and offset matching when used in multichannel applications, or in applications where full-scale range adjustment is required.

The ADS822 and ADS825 employ digital error correction techniques to provide excellent differential linearity for demanding imaging applications.
