DATASHEET
ISL28190, ISL28290
Single and Dual Single Supply Ultra-Low Noise, Ultra-Low Distortion, Rail-to-Rail
Output, Op Amp
The ISL28190 and ISL28290 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 below ground (ground
sensing).
The ISL28190 and ISL28290 are unity gain stable with an
input referred voltage noise of 1nV/Hz. Both parts feature
0.00017% THD+N @ 1kHz.
The ISL28190 is available in the space-saving 6 Ld UTDFN
(1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28290 is
available in the 10 Ld UTQFN (1.8mmx1.4mm), 10 Ld MSOP
and 8 LD SOIC packages. All devices are guaranteed over
-40°C to +125°C.

NOTES:
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 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.
4. The part marking is located on the bottom of the part.
