・Recommended Capacitors
C1 = 100μF C2,C3 = 1μF
Although any external capacitors are basically not required, the (total) noise can be reduced by reducing the power line impedance and load line impedance.
BR-LB Series
These products are very low noise isolated DC-DC converters. The output noise of 3mVp-p has been realized by adopting a patented resonant circuit. Radiation noise is also suppressed by 5-side shielded metal case. Those are very reliable and are suitable for noise separation between analog and digital circuits. It is also suitable for the amplifier used in a measurement instrument, that amplifies small signals.
