General Description

The AD647 is an ultralow drift, dual JFET amplifier that combines high performance and convenience in a single package.

The AD647 uses the most advanced ion-implantation and laser wafer drift trimming technologies to achieve the highest performance currently available in a dual JFET.

Ion-implantation permits the fabrication of matched JFETs on a monolithic bipolar chip.
