ISL28210

Precision Low Noise JFET Operational Amplifiers

Product Status: Mass Production

OVERVIEW

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 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 -40°C to +125°C.
