FN6156.2

Single and Dual Ultra-Low Noise,

Rail-to-Rail, Op Amp

Features

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

The ISL28191 and ISL28291 are tiny single and dual

ultra-low noise, ultra-low distortion operational amplifiers.

Fully specified to operated 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).

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

• 61MHz -3dB bandwidth

• 630µV maximum offset voltage

• 3µA input bias current

• 100dB typical CMRR

The ISL28191 and ISL28291 are unity gain stable with an

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

• 3V to 5.5V single supply voltage range

• Rail-to-rail output

and 3 harmonic distortion of -76dBc and -70dBc,

respectively.

• Ground Sensing

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

(1.6mm x 1.6mm) and SOT-23 packages. The ISL28291 is

available in the 10 Ld µTQFN (1.8mm x 1.4mm) and MSOP

packages. All devices are guaranteed over -40°C to +125°C.

• Enable pin

• Pb-free plus anneal available (RoHS compliant)

Applications

Ordering Information

• Low noise signal processing

• Low noise microphones/preamplifiers

• ADC buffers

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100% matte

tin plate termination finish, which are 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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
