Overview
The AD706JR-REEL is a dual, low power, bipolar operational amplifier produced by Analog Devices Inc. This component is notable for its high DC precision and low input bias current, similar to that of a JFET amplifier, but with the added benefit of lower input bias current drift over temperature, characteristic of bipolar amplifiers.
The AD706JR-REEL is available in an 8-lead SOIC package and is rated over the commercial temperature range of 0°C to +70°C. It is internally compensated for unity gain and is suitable for applications requiring low noise and high precision.
