The ADS823 and ADS826 are pipeline, CMOS Analog-to-Digital Converters (ADCs) 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 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.
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, communications, video, and test instrumentation. The ADS823 and ADS826 offer power dissipation of 265mW and also provide a power-down mode, thus reducing power dissipation to only 20mW.
The ADS823 and ADS826 are specified at a maximum sampling frequency of 60MHz and a single-ended input range of 1.5V to 3.5V. The ADS823 and ADS826 are available in an SSOP-28 package and are pin-compatible with the 10-bit, 40MHz ADS822 and ADS825, and the 10-bit, 75MHz ADS828.
