... When large transient pulses (>1 V) are applied at the positive terminal of amplifiers (such as the OP27, LT1007, OPA227, and AD8671) with back-to-back diodes at the input stage, the use of a resistor in the feedback loop is recommended to avoid having the amplifier load the signal generator. The feedback resistor should be at least 500 Ω ...

... However, because they have low input current noise, they can also be used in circuits with substantial source resistance ±15V SY Figure 34 shows the voltage noise, current noise, thermal noise, and total rms noise of the AD8671 as a function of the source resistance.

... However, when configured in unity gain, driving very large loads can cause unwanted ringing or instability. Figure 36 shows the output of the AD8671 with a capacitive load of 1 nF. If heavier loads are used in low closed-loop gain or unity-gain configurations recommended to use external compensation as shown in the circuit in Figure 37 ...

... AD8671 GPS RECEIVER GPS receivers require low noise to minimize RF effects. The precision of the AD8671 makes it an excellent choice for such applications. Its very low noise and wide bandwidth make it suitable for band-pass and low-pass filters without the penalty of high power consumption. ...
