PRODUCT 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. Laser wafer drift trimming trims both the initial offset voltage and its drift with temperature to provide offsets as low as 100 μV (250 μV max) and drifts of 2.5 μV/°C max.
