Overview
The AD8031ART-REEL7, produced by Analog Devices Inc., is a single-supply, voltage feedback operational amplifier. It is part of the AD8031 series, which includes both single (AD8031) and dual (AD8032) versions. This amplifier is designed for high-speed performance, featuring an 80 MHz small signal bandwidth, a 30 V/μs slew rate, and a settling time of 125 ns to 0.1%. It operates on a low power consumption of less than 4.0 mW from a single 5 V supply, making it ideal for battery-operated systems and high component density applications.
