ADS5221

The ADS5221 is a pipeline, CMOS Analog-to-Digital Converter (ADC) that operates from a single +3.3V power supply. 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 12-bit quantizer, high bandwidth track-and-hold, and a high accuracy internal reference; it also allows for the user to disable the internal reference and utilize external references, providing excellent gain and offset matching in multi-channel applications or in applications where full-scale range adjustment is required.

The ADS5221 employs digital error correction techniques to enable 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. It offers power dissipation of 285mW and also provides two power-down modes. The ADS5221 is specified at a maximum sampling frequency of 65MHz and a differential input range of 1V to 2V. The product is available in a TQFP-48.
