ISL28191 & ISL28291 Operational Amplifiers

Renesas Electronics ISL28191 and ISL28291 Single and Dual Operational Amplifiers offer ultra-low noise and low distortion rail-to-rail output, in a tiny size. The ISL28191 Op Amps are fully specified to operate down to +3V single supply. The devices also feature outputs that swing rail-to-rail and an input common-mode voltage that extends to ground (ground sensing).
