Data Sheet
ISL28191, ISL28291
April 13, 2007
FN6156.2
Single and Dual Ultra-Low Noise,
Rail-to-Rail, Op Amp
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).
The ISL28191 and ISL28291 are unity gain stable with an
input referred voltage noise of 1.7nV/√Hz. Both parts feature
2nd and 3rd harmonic distortion of -76dBc and -70dBc,
respectively.
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.

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.
