Precision Single and Dual Low Noise
Operational Amplifiers
The ISL28127 and ISL28227 are very high precision
amplifiers featuring very low noise, low offset voltage, low
input bias current and low temperature drift making them the
ideal choice for applications requiring both high DC accuracy
and AC performance. The combination of precision, low
noise, and small footprint provides the user with outstanding
value and flexibility relative to similar competitive parts.
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls, and industrial controls.
The ISL28127 single is available in an 8 Ld SOIC package.
The ISL28227 dual amplifier will be offered in 8 Ld SOIC
package. All devices are offered in standard pin
configurations and operate over the extended temperature
range to -40°C to +125°C.

NOTE: 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.
