ISL28110_1012 Datasheet, PDF (1/25 Pages) Intersil Corporation – Precision Low Noise JFET Operational Amplifiers

Precision Low Noise JFET Operational Amplifiers
ISL28110, ISL28210
The ISL28110, ISL28210, are single and dual JFET
amplifiers featuring low noise, high slew rate, low input
bias current and offset voltage, making them the ideal
choice for high impedance applications where precision
and low noise are important. The combination of
precision, low noise, and high speed combined with a
small footprint provides the user with outstanding value
and flexibility relative to similar competitive parts.
Applications for these amplifiers include precision medical
and analytical instrumentation, sensor conditioning,
precision power supply controls, industrial controls and
photodiode amplifiers.
The ISL28110 single amplifier is available in the 8 Ld
SOIC, TDFN, and MSOP packages. The ISL28210 dual
amplifier is available in the 8 Ld SOIC and TDFN
packages. All devices are offered in standard pin
configurations and operate over the extended
temperature range from -40°C to +125°C.
