NOTES
1Absolute maximum ratings are limiting values to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability.
2Output is short-circuit protected; for maximum reliability, 90 mA continuous current should not be exceeded.
3Typical thermal impedances (part soldered onto board; no air flow):
     Ceramic DIP: JA = 100°C/W; JC = 30°C/W
     Plastic SOIC: JA = 125°C/W; JC = 45°C/W
     Plastic DIP: JA = 90°C/W; JC = 45°C/W
4Temperature shown is for surface mount devices, mounted by vapor phase soldering. Throughhole devices (ceramic and plastic DIPs) can be soldered at +300°C for 10 seconds.


Description

The AD9621 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, 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 AD9621 exhibits extraordinarily accurate and fast pulse response characteristics (7 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 AD9621 offers performance not previously available in a monolithic operational amplifier.

Other members of the AD962X amplifier family are the AD9622 (G = +2), AD9623 (G = +4), and the AD9624 (G = +6). 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.

The AD9621 is offered in industrial and military temperature ranges. Industrial versions are available in plastic DIP, SOIC, and cerdip; MIL versions are packaged in cerdips.
