... Supply current is typically 95µA and noise is 4.5µV benefitting precision, low noise portable P-P applications such as handheld meters and instruments. Data Converters in particular can utilize the ISL21009MEP as an external voltage reference. Low power DAC and ADC circuits will realize maximum resolution with lowest noise. www.DataSheet4U.com 50µA -50µ ...

... 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 ISL21009MEP is not designed to drive heavily capactive loads, so for load capacitances above 0.001µF, the noise reduction network shown in Figure 44 is recommended. This network reduces noise significantly over the full bandwidth. Noise is reduced to less than 20µ ...
