Low-Power, Rail-to-Rail I/O Op Amp
General Description
The MAX44280 offers a unique combination of high
speed, precision, low noise, and low-voltage operation
making it ideally suited for a large number of signal pro-
cessing functions such as filtering and amplification of
signals in portable and industrial equipment.
The amplifier features an input offset of less than 50FV
and a high-gain bandwidth product of 50MHz while
maintaining a low 1.8V supply rail. The device is internally
compensated for gains of 5V/V or greater. The device’s
rail-to-rail input/outputs and low noise guarantee maxi-
mum dynamic range in demanding applications such
as 12- to 16-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 MAX44280 includes a fast-power-on shutdown mode
for further power savings.
The MAX44280 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 MAX44280 is available in a small,
6-pin SC70 package and is also available in a 1mm x
1.5mm thin µDFN (ultra-thin LGA) package.
