The MAX44261 offers a unique Saves Board Space on-demand calibration pin where the user can invoke self- Small, 2mm x 2mm SC70 and 1mm x 1.5mm Thin trimming of the input offset voltage. The MAX44263 is a DFN (MAX44260) and SOT23 (MAX44259) dual amplifier. Packages The family of parts operates from a supply range of 1.8V Wide Supply Range from 1.8V to 5.5V Simplifies to 5.5V over the -40NC to +125NC temperature range Power-Supply Requirements and can operate down to 1.7V over the 0NC to +70NC Applications temperature range. The MAX44259 is offered in a 5-pin SOT23 package. The MAX44260/MAX44261 are avail- Notebooks able in small, 6-pin SC70 packages. The MAX44260 is 3G/4G Handsets also available in a 1mm x 1.5mm thin DFN (ultra-thin Portable Media Players LGA) package. The MAX44263 is available in a small Portable Medical Instruments 8-pin SC70 package.
