The AD8044 is a quad, low power, voltage feedback, high speed amplifier designed to operate on +3 V, +5 V, or ±5 V supplies. It has true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail.
The AD8044 quad amplifier from Analog Devices offers a wide 150 MHz -3 dB bandwidth, 170 V/µs slew rate, and rail‑to‑rail output swing within 25 mV of each rail. It operates from single‑supply voltages of 3 V to 12 V and draws only 13.1 mA per amplifier, making it suitable for video electronics, active filters, and high‑speed portable equipment.
Key features include low distortion (‑68 dB THD at 5 MHz), high output current capability (30 mA), and flexible packaging options (14‑lead PDIP or SOIC). The datasheet provides detailed electrical specifications, absolute maximum ratings, and ordering information for various temperature‑rated parts.
