描述

The ISL28291 is a tiny, dual, ultra-low noise, ultra-low distortion operational amplifier. It is fully specified to operate down to +3V single supply. This amplifier has outputs that swing rail-to-rail and an input common mode voltage that extends to ground (ground sensing). The device is unity gain stable with an input referred voltage noise of 1.7nV/√Hz. Both parts feature 0.00018% THD+N at 1kHz. The ISL28291 is available in the 8 Ld SOIC, 10 Ld 1.8mm x 1.4mm UTQFN and 10 Ld MSOP packages. All devices are guaranteed over -40 °C to +125 °C.
