FEATURES q HIGH SNR: 57d B q q q q EXTERNAL REFERENCE LOW POWER: 140m W ADJUSTABLE FULL SCALE RANGE POWER DOWN DESCRIPTION The ADS902 is a high speed pipelined analog-todigital converter that is specified to operate from a single +5V supply. This converter includes a wide bandwidth track/hold and a 10-bit quantizer. The performance is specified with a single-ended input range of 2.25V to 3.25V, or 2V to 4V. The input range is set by the external reference values. The ADS902 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 telemunications, video and test instrumentation applications. This high performance A/D converter is specified to operate at a 30MHz sampling rate. The ADS902 is available in a 28-pin SSOP package. q 28-PIN SSOP PACKAGE APPLICATIONS q BATTERY POWERED EQUIPMENT q CAMCORDERS q PORTABLE TEST EQUIPMENT q PUTER SCANNERS q MUNICATIONS CLK ADS902 Timing Circuitry LVDD T/H Pipeline A/D Error Correction Logic 3-State Outputs 10-Bit Digital Data Reference Ladder REFT CM REFB Pwrdn International Airport Industrial Park - Mailing Address: PO Box 11400, Tucson, AZ 85734 - Street Address: 6730 S.
