Precision Low Noise JFET Operational Amplifiers
ISL28110, ISL28210 Features 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. Wide supply range . 9V to 40V 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 and the ISL28210 dual
amplifiers are available in the 8 Ld SOIC package. All devices
are offered in standard pin configurations and operate over the
extended temperature range from -40В°C to +125В°C. Low voltage noise . 6nV/в€љHz Input bias current . 2pA High slew rate . 23V/Вµs High bandwidth 12.5MHz Low input offset . 300ВµV, Max Offset drift .
