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 µTDFN
(1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28290
is available in the 10 Ld µTQFN (1.8mmx1.4mm) and 10 Ld
MSOP packages. All devices are guaranteed over -40°C to
+125°C.

NOTES:
1. 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.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets; molding compounds/die attach materials
