This converter provides excellent performance with a single-ended input and can be operated with a differential input for added spurious performance. This high performance converter includes a 10-bit quantizer, high bandwidth track/hold, and a high accuracy internal reference. It also allows 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 multi-channel applications or in applications where full scale range adjustment is required. The ADS824 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. Its low distortion and high SNR give the extra margin needed for medical imaging, communications, video, and test instrumentation. The ADS824 offers power dissipation of 315mW and also provides a power-down mode, thus reducing power dissipation to only 20mW. The ADS824 is specified at a maximum sampling fre...
