MAX44259/MAX44260/

MAX44261/MAX44263

1.8V, 15MHz Low-Oﬀset,

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

General Description

Beneﬁts and Features

● Low Noise for Higher System Accuracy

• 12.7nV/√Hz Input Voltage-Noise Density

• 1.2fA/√Hz Input Current-Noise Density

• 50µV (max) VOS at +25°C

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 filter-

ing and amplification of signals in portable and industrial

equipment.

• 110dB Total Harmonic Distortion

● 15MHz Unity-Gain Bandwidth Enables for High-

Bandwidth Applications

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 dis-

tortion is absent due to an optimized input stage with an

ultra-quiet charge pump.

● Low Power Extends the Battery Life of Portable

Equipment

• 500fA Low Input Bias Current

• 750µA Quiescent Current per Ampliﬁer

• < 1µA Supply Current in Shutdown

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.

● On-Demand V

Self-Calibration (MAX44261)

● Saves Board Space

• Small, 2mm x 2mm SC70 and 1mm x 1.5mm Thin

µDFN (MAX44260) and SOT23 (MAX44259)

Packages

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.

● Wide Supply Range from 1.8V to 5.5V Simplifies

Power-Supply Requirements

Applications

● Notebooks

● 3G/4G Handsets

● Portable Media Players

● Portable Medical Instruments

● Battery-Operated Devices

● Analog-to-Digital Converter Buﬀers

● Transimpedance Ampliﬁers
