This document is about Intersil HA-2544 50MHz, Video Operational Amplifier. It offers high voltage gain (6kV/V) and high phase margin (65 degrees), while maintaining tight gain flatness over the video bandwidth.
The HA-2544 is a fast, unity‑gain stable, monolithic operational amplifier designed for video and high‑speed signal applications. It offers a 50 MHz gain‑bandwidth, 150 V/µs slew rate, 10 mA supply current, and a phase margin of about 65°.
The device is supplied in an 8‑lead PDIP package and is intended for use in video test equipment, imaging systems, radar displays, and other precision video or high‑speed circuits. Recommended loading for optimal video performance is a 1 kΩ load.
