19-4802; Rev 0; 10/00 ILABLE N KIT AVA EVALUATIO 10-Bit, 105Msps, Single +3.3V, Low-Power ADC with Internal Reference General Description The MAX1449 +3.3V, 10-bit analog-to-digital converter (ADC) Features a fully differential input, a pipelined 10stage ADC architecture with wideband track-and-hold (T/H), and digital error correction incorporating a fully differential signal path. The ADC is optimized for lowpower, high-dynamic performance in imaging and digital munications applications. The converter operates from a single +2.7V to +3.6V supply, consuming only 186m W while delivering a 58.5d B (typ) signalto-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a -3d B 400MHz bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1449 Features a 5µA power-down mode for idle periods. An internal +2.048V precision bandgap reference is used to set the ADC’s full-scale range. A flexible reference structure allow’s the user to supply a buffered, direct, or externally derived reference for applications requiring increased accuracy or a different input voltage range. Lower speed, pin-patible versions of the MAX1449 are also available. Refer to the MAX1444 data sheet for a 40Msps version, the MAX1446 data sheet for a 60Msps version, and the MAX1448 data sheet for 80Msps. The MAX1449 has parallel, offset binary, CMOS-patible, three-state outputs that can be operated from +1.7V to +3.6V to allow flexible interfacing. The device is available in a 5mm x 5mm 32-pin TQFP package and is specified over the extended industrial (-40°C to +85°C) temperature range. o Single +3.3V Operation o Excellent Dynamic Performance 58.5d B SNR at f IN = 20MHz 72d Bc SFDR at f IN = 20MHz o Low Power 62m A (Normal Operation) 5µA (Shutdown Mode) o Fully Differential Analog Input o Wide 2Vp-p Differential Input Voltage Range o 400MHz -3d B Input Bandwidth o On-Chip +2.048V Precision Bandgap Reference o CMOS-patible...
