Overview
The AD8648ARZ-REEL7 is a quad-channel, rail-to-rail, input and output, single-supply operational amplifier produced by Analog Devices Inc. This amplifier is distinguished by its low offset voltage, wide signal bandwidth, low input voltage, and low current noise. The combination of a 24 MHz bandwidth, low offset, low noise, and very low input bias current makes the AD8648ARZ-REEL7 highly versatile and suitable for a wide range of applications.
It offers high output drive capability, which is particularly beneficial for audio line drivers and other low impedance applications. The amplifier is also unity gain stable and features no phase reversal, making it reliable in various operational scenarios.
