Single and Dual Single Supply Ultra-Low
Noise, Low Distortion Rail-to-Rail Output,
Op Amp
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 µTDFN
(1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28291
is available in the 8 Ld SOIC, 10 Ld 1.8mmx1.4mm µTQFN
and 10 Ld MSOP packages. All devices are guaranteed over
-40°C to +125°C.
