Overview
The AD8034ART-REEL7 from Analog Devices Inc. is a dual operational amplifier belonging to the FastFET™ family. These amplifiers are voltage feedback types with FET inputs, offering ease of use and excellent performance. The AD8034 is specifically a dual amplifier, contrasting with the AD8033 which is a single amplifier. These amplifiers are designed using Analog Devices' proprietary XFCB process, incorporating JFET devices to enhance performance in low input bias current and high bandwidth applications.
The AD8034ART-REEL7 is notable for its wide supply voltage range of 5 V to 24 V, making it versatile for various applications. It features rail-to-rail output, low noise (11 nV/√Hz and 0.7 fA/√Hz), and high speed (80 MHz bandwidth and 80 V/μs slew rate), making it suitable for a broad range of uses.
