Description
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.
See a parametric table of the complete family of pin-compatible, 10-bit high-speed ADCs.
The MAX1444 has parallel, offset binary, CMOS-compatible 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.
