Overview
The AD706JR, produced by Analog Devices Inc., is a dual low drift operational amplifier (op amp) known for its high DC precision and low input bias current. This bipolar op amp utilizes superbeta bipolar input transistors, achieving picoampere input bias current levels similar to FET input amplifiers at room temperature. It is particularly suited for applications requiring low noise and high precision, such as precision instrumentation and low frequency active filters.
