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.
