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 V (250 V max) and drifts of 2.5 V/C max. In addition to outstanding individual amplifier performance, the AD647 offers guaranteed and tested matching performance on critical parameters such as offset voltage, offset voltage drift and bias currents.
