MAX44280

1.8V, 50MHz, Low-Offset,

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

General Description

Features

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.

S Low 1.8V Supply Rail Over the -40°C to +125°C

Range

S 1.7V Supply Rail Over the 0°C to +70°C Range

S 50MHz Bandwidth

S Low 12.7nV/√Hz Input Voltage-Noise Density

S Low 1.2fA/√Hz Input Current-Noise Density

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.

S Low 50µV (max) V

at +25°C

S 500fA Low Input Bias Current

S 750µA Quiescent Current per Amplifier

S < 1µA Supply Current in Shutdown

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

µDFN Packages

S Low 110dB Total Harmonic Distortion

S 5V/V Minimum Stable Gain

The MAX44280 includes a fast-power-on shutdown mode

for further power savings.

Applications

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.
