... T bandwidth, slew rate, and peaking of the ADA4891-1/ADA4891-2/ is ADA4891-3/ADA4891-4. Note that as the gain increases, the T small-signal bandwidth decreases expected from the gain bandwidth product relationship. In addition, the phase margin improves with higher gains, and the amplifier becomes more stable ...

... ADA4891-1/ADA4891-2/ADA4891-3/ADA4891-4 LAYOUT, GROUNDING, AND BYPASSING POWER SUPPLY BYPASSING Power supply pins are additional op amp inputs, and care must be taken so that a noise-free, stable dc voltage is applied. The purpose of bypass capacitors is to create a low impedance path from the supply to ground over a range of frequencies, thereby shunting or filtering the majority of the noise to ground ...
