ISL28290

Dual Supply Ultra-Low Noise, Ultra-Low Distortion, Rail-to-Rail Output, Op Amp

Product Status: Mass Production

OVERVIEW

The ISL28190 and ISL28290 are tiny single and dual ultra-low noise, ultra-low distortion operational amplifiers. Fully specified to operated down to +3V single supply. These amplifiers have outputs that swing rail-to-rail, and an input common mode voltage that extends below ground (ground sensing).

The ISL28190 and ISL28290 are unity gain stable with an input referred voltage noise of 1nV/√Hz. Both parts feature 0.00017% THD+N @ 1kHz.

The ISL28190 is available in the space-saving 6 Ld UTDFN (1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28290 is available in the 10 Ld UTQFN (1.8mmx1.4mm) , 10 Ld MSOP and 8 LD SOIC packages. All devices are guaranteed over -40°C to +125°C.
