19-1745; Rev 1; 11/03 KIT ATION EVALU E L B AVAILA 10-Bit, 40Msps, 3.0V, Low-Power ADC with Internal Reference General Description Features o Single 3.0V Operation o Excellent Dynamic Performance 59.5d B SNR at f IN = 20MHz 74d Bc SFDR at f IN = 20MHz o Low Power 19m 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 Three-State Outputs o 32-Pin TQFP Package o Evaluation Kit Available The MAX1444 10-bit, 3V analog-to-digital converter (ADC) Features a pipelined 10-stage ADC architecture with fully differential wideband track-and-hold (T/H) input and digital error correction incorporating a fully differential signal path. This ADC is optimized for lowpower, high dynamic performance applications in imaging and digital munications. The MAX1444 operates from a single 2.7V to 3.6V supply, consuming only 57m W while delivering a 59.5d B signal-to-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a 400MHz -3d B bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1444 Features a 5µA power-down mode for idle periods. An internal 2.048V precision bandgap reference is used to set the ADC full-scale range. A flexible reference structure allows the user to supply a buffered, direct, or externally derived reference for applications requiring increased accuracy or a different input voltage range. Higher speed, pin-patible versions of the MAX1444 are also available. Please refer to the MAX1446 data sheet (60Msps) and the MAX1448 data sheet (80Msps). The MAX1444 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 5x5mm 32-pin TQFP package and is specified over the extended industrial (-40°C to +85°C) temperature...
