MAX44259/MAX44260/MAX44261/MAX44263

1.8V, 15MHz Low-Offset,

Low-Power, Rail-to-Rail I/O Op Amps

General Description

The MAX44259/MAX44260/MAX44261/MAX44263 offer a

unique combination of high speed, precision, low noise,

and low-voltage operation making them ideally suited

for a large number of signal processing functions such

as filtering and amplification of signals in portable and

industrial equipment.

The devices’ rail-to-rail input/outputs and low noise

guarantee maximum dynamic range in demanding appli-

cations 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 MAX44263

is a dual amplifier.

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

temperature range. The MAX44259 is offered in a 5-pin

SOT23 package. The MAX44260/MAX44261 are avail-

able in small, 6-pin SC70 packages. The MAX44260 is

also available in a 1mm x 1.5mm thin µDFN (ultra-thin

LGA) package. The MAX44263 is available in a small

8-pin SC70 package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-

tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.
