Overview
The AD818AR-REEL from Analog Devices Inc. is a low-cost, low-power video operational amplifier designed for high-speed applications. It features a 130 MHz 3 dB bandwidth and a 500 V/μs slew rate, making it suitable for various video and high-speed signal processing tasks. The AD818 is available in an 8-lead SOIC package and can operate with either a single +5 V power supply or dual supplies ranging from ±5 V to ±15 V. This flexibility, combined with its low supply current of 7.5 mA, makes it an ideal choice for power-sensitive applications.
