Rev 10.00
July 22, 2014 Single and Dual Single Supply Ultra-Low Noise, Low Distortion Rail-to-Rail
Output, Op Amp
The ISL28191 and ISL28291 are tiny single and dual ultra-low
noise, ultra-low distortion operational amplifiers. They are fully
specified to operate down to +3V single supply. These
amplifiers have 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/пѓ–Hz. Both parts feature
0.00018% THD+N at 1kHz. Features 1.7nV/в€љHz input voltage noise at 1kHz 1kHz THD+N typical 0.00018% at 2VP-P VOUT Harmonic Distortion -76dBc, -70dBc, fo = 1MHz 61MHz -3dB bandwidth 630ВµV maximum offset voltage 3ВµA input bias current 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. All devices are guaranteed over -40В°C
to +125В°C. 100dB typical CMRR Ordering Information Enable pin (not available in the 8 Ld SOIC package option) PART NUMBER
