12-bit, 40MSPS, +3.3V Analog-to-Digital Converter
The ADS5220 is a pipeline, CMOS Analog-to-digital Converter (ADC) that operates from a single +3.3V power supply. This converter CAN be operated with a single-ended input or differential input. The ADS5220 includes a 12-bit quantizer, high bandwidth track-and-hold, and an internal reference. It also allows the user to disable the internal reference and utilize external references which provide excellent gain and offset matching when used in multi-channel applications or in applications where full-scale range adjustment is required.
The ADS5220 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 ADS5220 offers power dissipation of 195mW and also provides two power-down modes.
The ADS5220 is specified at a maximum sampling frequency of 40MSPS and a differential input range of 1V to 2V. The ADS5220 is available in a TQFP-48 package.
