FN6156.5  
Single and Dual Single Supply Ultra-Low  
Noise, Low Distortion Rail-to-Rail Output,  
Op Amp  
Features  
• 1.7nV/√Hz input voltage noise at 1kHz  
• 1kHz THD+N typical 0.00018% at 2V  
V
P-P OUT  
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).  
• Harmonic Distortion -76dBc, -70dBc, f = 1MHz  
o
• 61MHz -3dB bandwidth  
• 630µV maximum offset voltage  
• 3µA input bias current  
• 100dB typical CMRR  
The ISL28191 and ISL28291 are unity gain stable with an  
input referred voltage noise of 1.7nV/√Hz. Both parts feature  
0.00018% THD+N at 1kHz.  
• 3V to 5.5V single supply voltage range  
• Rail-to-rail output  
The ISL28191 is available in the space-saving 6 Ld µTDFN  
(1.6mmx1.6mm) and 6 Ld SOT-23 packages. The ISL28291  
is available in the 8 Ld SOIC, 10 Ld 1.8mmx1.4mm µTQFN  
and 10 Ld MSOP packages. All devices are guaranteed over  
-40°C to +125°C.  
• Ground Sensing  
• Enable pin (not available in the 8 Ld SOIC package  
option)  
• Pb-free (RoHS compliant)

NOTES:  
1. These Intersil Pb-free plastic packaged products employ special  
Pb-free material sets; molding compounds/die attach materials  
and 100% matte tin plate PLUS ANNEAL - e3 termination finish,  
which is RoHS compliant and compatible with both SnPb and Pb-  
free soldering operations. Intersil Pb-free products are MSL  
classified at Pb-free peak reflow temperatures that meet or exceed  
the Pb-free requirements of IPC/JEDEC J STD-020.  
2. These Intersil Pb-free plastic packaged products employ special  
Pb-free material sets; molding compounds/die attach materials  
and NiPdAu plate - e4 termination finish, which is RoHS compliant  
and compatible with both SnPb and Pb-free soldering operations.  
Intersil Pb-free products are MSL classified at Pb-free peak reflow  
temperatures that meet or exceed the Pb-free requirements of  
IPC/JEDEC J STD-020.
