GENERAL DESCRIPTION
FEATURES
o Single 3.0V Operation o Excellent Dynamic Performance 59.5dB SNR at fIN = 20MHz 74dBc SFDR at fIN = 20MHz o Low Power 19mA (Normal Operation) 5µA (Shutdown Mode) o Fully Differential Analog Input o Wide 2Vp-p Differential Input Voltage Range o 400MHz -3dB Input Bandwidth o On-Chip 2.048V Precision Bandgap Reference o CMOS-Compatible Three-State Outputs o 32-Pin TQFP Package o Evaluation Kit Available MAX1444 The fully differential input stage has a 400MHz -3dB 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-compatible versions of the MAX1444 are also available. Please refer to the MAX1446 data sheet (60Msps) and the MAX1448 data sheet (80Msps).
