Product Summary

The AD8512F is a quad-precision JFET amplifier that features low offset voltage, input bias current, input voltage noise, and input current noise. The combination of low offsets, low noise, and very low input bias currents makes the amplifier especially suitable for high impedance sensor amplification and precise current measure-ments using shunts. The applications of the AD8512F include instrumentation, multipole filters, precision current measurement, photodiode amplifiers, sensors, audio.
