The MAX44260/MAX44261 offer a unique combination of

high speed, precision, low noise, and low-voltage opera-

tion making them ideally suited for a large number of

signal processing functions such as filtering and ampli-

fication of signals in portable and industrial equipment.

The amplifiers feature an input offset of less than 50FV

and a high-gain bandwidth product of 15MHz while

maintaining a low 1.8V supply rail. The devices’ rail-to-

rail input/outputs and low noise guarantee maximum

dynamic range in demanding applications such as 12- to

14-bit SAR ADC drivers. Unlike traditional rail-to-rail input

structures, input crossover distortion is absent due to an

optimized input stage with an ultra-quiet charge pump.

The MAX44260 includes a fast-power-on shutdown mode

for further power savings. The MAX44261 offers a unique

on-demand calibration pin where the user can invoke

self-trimming of the input offset voltage.

The family of parts operates from a supply range of 1.8V

to 5.5V over the -40NC to +125NC temperature range and

can operate down to 1.7V over the 0NC to +70NC tem-

perature range. The MAX44260/MAX44261 are available

in small, 6-pin SC70 packages.
