ISL28191, ISL28291
Single and Dual Single Supply Ultra-Low Noise, Low Distortion Rail-to-Rail Output, Op Amp
FN6156 Rev 10.00 July 22, 2014
The ISL28191 and ISL28291 are tiny single and dual ultra-low noise, ultra-low distortion operational amplifiers. They are fully specified to operate 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 0.00018% THD+N at 1kHz.
The ISL28191 is available in the space-saving 6 Ld UTDFN (1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28291 is available in the 8 Ld SOIC, 10 Ld 1.8mmx1.4mm UTQFN and 10 Ld MSOP packages.
