ISL28107, ISL28207

Precision Single and Dual Low Noise

Operational Amplifiers

The ISL28107 and ISL28207 are single and dual amplifiers

featuring low input bias current, low noise, 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 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.
