Renesas Electronics 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).
The ISL28191 and ISL28291 are unity-gain stable with an input-referred voltage noise of 1.7nV/√Hz. The Op Amps 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. Renesas Electronics ISL28191 and ISL28291 Single and Dual Operational Amplifiers are guaranteed over -40°C to +125°C.
