The AD841 is a wideband, unity-gain stable, fast settling op amp. It features 40MHz unity-gain bandwidth, 110ns settling time to 0.01%, 300V/µs slew rate and 4.7MHz full power bandwidth. It is suitable for high speed signal conditioning, video and pulse amplifiers, data acquisition systems, line drivers and active filters.
The AD841 is a high‑speed, high‑precision operational amplifier from Analog Devices. It offers a 40 MHz unity‑gain bandwidth, 300 V/µs slew rate, low input offset (1 mV max) and low input voltage noise (13 nV/√Hz typ), making it suitable for video, pulse and data‑acquisition applications.
The device is available in several packages (14‑pin DIP, TO‑8, LCC) and operates from a +5 V to +18 V supply with a quiescent current of 12 mA. It can drive up to 50 mA output current and handle capacitive loads up to 20 pF without performance degradation.
