Overview
The AD8044ARZ-14 from Analog Devices Inc. is a quad, low power, voltage feedback, high-speed amplifier. It is designed to operate on +3 V, +5 V, or ±5 V supplies, offering true single-supply capability. The amplifier features an input voltage range that extends 200 mV below the negative rail and within 1 V of the positive rail. This makes it particularly useful for applications requiring high speed and low power consumption, such as video electronics, active filters, and portable equipment.
