ADS5220 ADS 522 0 SBAS261A – APRIL 2003 – REVISED MARCH 2004 12-Bit, 40MSPS Sampling, +3.3V ANALOG-TO-DIGITAL CONVERTER FEATURES q q q q q q q q q HIGH SNR: 70dB HIGH SFDR: 88dBFS LOW POWER: 195mW INTERNAL/EXTERNAL REFERENCE OPTION SINGLE-ENDED OR FULLY DIFFERENTIAL ANALOG INPUT PROGRAMMABLE INPUT RANGE LOW DNL: 0.3LSB SINGLE +3.3V SUPPLY OPERATION TQFP-48 PACKAGE DESCRIPTION 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. APPLICATIONS q WIRELESS LOCAL LOOP q COMMUNICATIONS q MEDICAL IMAGIN...
