DATASHEET

ISL28191, ISL28291

Single and Dual Single Supply Ultra-Low Noise, Low Distortion Rail-to-Rail

Output, Op Amp

FN6156

Rev 10.00

July 22, 2014

The ISL28191 and ISL28291 are tiny single and dual ultra-low

Features

noise, ultra-low distortion operational amplifiers. They are fully

• 1.7nV/√Hz input voltage noise at 1kHz

specified to operate down to +3V single supply. These

amplifiers have outputs that swing rail-to-rail and an input

common mode voltage that extends to ground

(ground sensing).

• 1kHz THD+N typical 0.00018% at 2V

P-P OUT

• Harmonic Distortion -76dBc, -70dBc, f = 1MHz

• 61MHz -3dB bandwidth

The ISL28191 and ISL28291 are unity gain stable with an

input referred voltage noise of 1.7nV/Hz. Both parts feature

0.00018% THD+N at 1kHz.

• 630µV maximum offset voltage

• 3µA input bias current

• 100dB typical CMRR

The ISL28191 is available in the space-saving 6 Ld UTDFN

(1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28291 is

available in the 8 Ld SOIC, 10 Ld 1.8mmx1.4mm UTQFN and

10 Ld MSOP packages. All devices are guaranteed over -40°C

to +125°C.

• 3V to 5.5V single supply voltage range

• Rail-to-rail output

• Ground Sensing

• Enable pin (not available in the 8 Ld SOIC package option)

• Pb-free (RoHS compliant)

1. Please refer to TB347 for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is

RoHS compliant and compatible with both SnPb and Pb-free

soldering operations). Intersil Pb-free products are MSL classified

at Pb-free peak reflow temperatures that meet or exceed the Pb-

free requirements of IPC/JEDEC J STD-020.

3. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets; molding compounds/die attach materials and

NiPdAu plate - e4 termination finish, which is RoHS compliant and
