Overview
The AD8051ARZ from Analog Devices Inc. is a single-channel, low-cost, high-speed voltage feedback operational amplifier. It offers true single-supply capability with an input voltage range extending 200mV below the negative rail and within 1V of the positive rail. Despite its low cost, the AD8051 provides excellent overall performance and versatility. The output voltage swings to within 25mV of each rail, ensuring maximum output dynamic range and excellent overdrive recovery. This amplifier is well-suited for high-speed applications such as video electronics, cameras, video switchers, and portable equipment.
