Precision Single, Dual and Quad Low Noise Operational
Amplifiers
ISL28107, ISL28207, ISL28407
The ISL28107, ISL28207 and ISL28407 are single, dual and
quad 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 is available in 8 Ld SOIC, MSOP and TDFN
packages. The ISL28207 is available in 8 Ld SOIC, MSOP and
TDFN packages. The ISL28407 is available in a 14 Ld SOIC
package. All devices are offered in standard pin configurations
and operate over the extended temperature range of -40°C to
+125°C.
