Precision Single and Dual Low Noise Operational
Amplifiers
ISL28107, ISL28207
The ISL28107 and ISL28207 are single and dual
amplifiers featuring low noise, low input bias current, and
low offset and temperature drift. This makes 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 ISL28107 single is available in an 8 Ld SOIC
package. The ISL28207 dual amplifier will be offered in
an 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.

NOTES:
1. Please refer to
TB347
for details on reel specifications.
2. 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.
