Bandwidth and equivalent input current noise are typical values, which depend on the source
capacitance. To achieve best possible bandwidth and noise performance, reduce the source
capacitance by using short cables at the input of the amplifier.
9
Positive Gain; current flowing into the amplifier input is considered positive, and produces a resulting
positive output voltage.
10
The bandwidth decreases as the output signal magnitude increases.
11
Operation above this specification is likely to permanently damage the amplifier.
