Overview
The AD8044ANZ, produced by Analog Devices Inc., is a quad low-power, voltage feedback, high-speed operational amplifier. It is designed to operate on a wide range of supply voltages, including +3 V, +5 V, or ±5 V, making it versatile for various applications. The amplifier features true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. This allows for maximum output dynamic range, with the output voltage swing extending to within 25 mV of each rail. The AD8044ANZ is fabricated on Analog Devices' proprietary eXtra-Fast Complementary Bipolar (XFCB) process, enabling high-frequency, low-distortion performance with low supply currents.
