The AD8044 is a quad, low power, voltage feedback, high-speed amplifier designed to operate on +3V, +5V, or ±5V supplies. It has true single-supply capability with an input voltage range extending 200mV below the negative rail and within 1V of the positive rail. The output voltage swing extends to within 25mV of each rail, providing the maximum output dynamic range.
The AD8044 quad amplifier from Analog Devices provides high‑speed performance with a 150 MHz -3 dB bandwidth, 170 V/µs slew rate, and low distortion. It operates from single‑supply voltages of 3 V to 12 V and offers rail‑to‑rail output swing within 25 mV of each rail, making it suitable for video, active‑filter and high‑speed portable applications.
Key features include low quiescent current (13.1 mA typical), 30 mA output drive capability, and a wide operating temperature range of –40 °C to +85 °C. The device is available in 14‑lead PDIP and SOIC packages with various temperature‑grade options.
