Overview
Description
The ISL28290 is a dual ultra-low noise, ultra-low distortion operational amplifier that is fully specified to operate down to +3V single supply. The amplifier has outputs that swing rail-to-rail, and an input common mode voltage that extends below ground (ground sensing). The ISL28290 is unity gain stable with an input referred voltage noise of 1nV/√Hz. The part features 0.00017% THD+N at 1kHz. The ISL28290 is available in 10-lead UTQFN (1.8mm x 1.4mm), 10-lead MSOP, and 8-lead SOIC packages. Device operation is guaranteed over -40 °C to +125 °C.
