ADS5221

SBAS262A – APRIL 2003 – REVISED DECEMBER 2003

12-Bit, 65MSPS Sampling, +3.3V

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● HIGH SNR: 70dB

The ADS5221 is a pipeline, CMOS Analog-to-Digital Con-

verter (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-perfor-

mance 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 off-

set matching in multi-channel applications or in applications

where full-scale range adjustment is required.

● HIGH SFDR: 88dBFS

● LOW POWER: 285mW

● INTERNAL/EXTERNAL REFERENCE OPTION

● SINGLE-ENDED OR

FULLY DIFFERENTIAL ANALOG INPUT

● FLEXIBLE DUTY CYCLE ADJUST CIRCUITRY

● LOW DNL: 0.5LSB

● SINGLE +3.3V SUPPLY OPERATION

● TQFP-48

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. The ADS5221 offers power dissi-

pation of 285mW and also provides two power-down modes.

APPLICATIONS

● WIRELESS LOCAL LOOP

● COMMUNICATIONS

The ADS5221 is specified at a maximum sampling fre-

quency of 65MHz and a differential input range of 1V to 2V.

The ADS5221 is available in a TQFP-48.

● MEDICAL IMAGING

● PORTABLE INSTRUMENTATION
