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/пѓ–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
-40В°C to +125В°C. FN6247
