Overview
The AD8034AR-REEL, produced by Analog Devices Inc., is a dual FastFET™ operational amplifier. This component is part of the AD8033/AD8034 series, which are voltage feedback amplifiers with FET inputs, known for their ease of use and excellent performance. The AD8034 is specifically a dual amplifier, contrasting with the single amplifier AD8033. These amplifiers utilize Analog Devices' proprietary XFCB process, incorporating JFET devices to achieve low input bias current, low distortion, and high bandwidth.
