Overview
The AD8034ARTZ-R2 is a dual operational amplifier from Analog Devices Inc., part of the AD8033/AD8034 series. These amplifiers are voltage feedback amplifiers with FET inputs, known for their ease of use and excellent performance. The AD8034 is specifically a dual amplifier, while the AD8033 is a single amplifier. Both are designed using Analog Devices' proprietary XFCB process, which incorporates JFET devices to enhance performance in low input bias current and high bandwidth applications.
The AD8034ARTZ-R2 offers high-speed operation with an 80 MHz bandwidth and an 80 V/μs slew rate, making it suitable for a variety of high-performance applications. It features a wide supply voltage range from 5 V to 24 V, rail-to-rail output, and low power consumption with a typical supply current of 3.3 mA per amplifier.
