OLE The AD9624 is one of a family of very high speed and wide bandwidth amplifiers utilizing a voltage feedback architecture. These amplifiers define a new level of performance for voltage feedback amplifiers, especially in the categories of large signal bandwidth, slew rate, settling, low distortion, and low noise. Proprietary design architectures have resulted in an amplifier family that combines the most attractive attributes of both current feedback and voltage feedback amplifiers. The AD9624 exhibits extraordinarily accurate and fast pulse response characteristics (8 ns settling to 0.1%) as well as extremely wide small and large signal bandwidth previously found only in current feedback amplifiers. When combined with balanced high impedance inputs and low input noise current more common to voltage feedback architectures, the AD9624 offers performance not previously available in a monolithic operational amplifier. *Protected by U.S. Patent 5,150,074 and others pending. Other members of the AD962X amplifier family are the AD9621 (G = +1), AD9622 (G = +2), and the AD9623 (G = +4). A separate data sheet is available from Analog Devices for each model. Each generic device has been designed for a different minimum stable gain setting, allowing users flexibility in optimizing system performance. Dynamic performance specifications such as slew rate, settling time, and distortion vary from model to model. The table below summarizes key performance attributes for the AD962X family and can be used as a selection guide. TE The AD9624 is offered in industrial and military temperature ranges. Industrial versions are available in plastic DIP, SOIC, and cerdip; MIL versions are packaged in cerdips. PRODUCT HIGHLIGHTS 1. Wide Large Signal Bandwidth 2. High Slew Rate 3. Fast Settling 4.
