The MAX1444 10-bit, 3V analog-to-digital converter(ADC) features a pipelined 10-stage ADC architecturewith fully differential wideband track-and-hold (T/H)input and digital error correction incorporating a fullydifferential signal path. This ADC is optimized for lowpower,high dynamic performance applications inimaging and digital communications. The MAX1444operates from a single 2.7V to 3.6V supply, consumingonly 57mW while delivering a 59.5dB signal-to-noiseratio (SNR) at a 20MHz input frequency. The fully differentialinput stage has a 400MHz -3dB bandwidth andmay be operated with single-ended inputs. In additionto low operating power, the MAX1444 features a 5μApower-down mode for idle periods.An internal 2.048V precision bandgap reference isused to set the ADC full-scale range. A flexible referencestructure allows the user to supply a buffered,direct, or externally derived reference for applicationsrequiring increased accuracy or a different input voltagerange.Higher speed, pin-compatible versions of the MAX1444are also available. Please refer to the MAX1446 datasheet (60Msps) and the MAX1448 data sheet(80Msps).The MAX1444 has parallel, offset binary, CMOS-compatiblethree-state outputs that can be operated from1.7V to 3.6V to allow flexible interfacing. The device isavailable in a 5x5mm 32-pin TQFP package and isspecified over the extended industrial (-40°C to +85°C)temperature range.________________________ApplicationsUltrasound ImagingCCD ImagingBaseband and IF DigitizationDigital Set-Top BoxesVideo Digitizing Applications
