... These limitations are addressed with circuit techniques discussed in other sections. Micropower Operation The ISL21009 consumes extremely low supply current due to the proprietary FGA technology. Low noise performance is achieved using optimized biasing techniques. Supply current is typically 95µA and noise is 4µV low noise portable applications such as handheld meters and instruments ...

... Load capacitance up to 1000pF can be added but will result in only marginal improvements in output noise and transient response. The output stage of the ISL21009 is not designed to drive heavily capactive loads, so for load capacitances above 0.001µF the noise reduction network shown in Figure 30 is recommended. ...
