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, highbandwidth track-and-hold, and a high-accuracy internal reference. They also allow for disabling the internal reference and utilizing external references. This external reference option provides excellent gain and offset matching when used in multi-channel applications or in applications where full-scale range adjustment is required. +VS ADS823 ADS826 CLK The ADS823 and ADS826 employ digital error correction techniques to provide excellent differential linearity for demanding imaging applications. Their low distortion and high SNR give the extra margin needed for medical imaging, communicati...
