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. The MAX44260 is also
available in a 1mm x 1.5mm thin μDFN (ultra-thin LGA)
package.
