Application Notes

Functions & Configuration

The LP5393 and LP5394 are low-noise DC power supplies with output noise voltage below 10µVrms.
Not only circuit technology but also the shielding construction inside the power supply enable this product to achieve the same low noise level as a battery.
The LP series power supplies are not merely low-noise outputs; compared with general DC power supplies, they also feature excellent temperature stability.
They are very suitable for measuring minute-signal circuits that are susceptible to noise and voltage stability.
They can normally be used as DC power supplies for low-noise preamplifiers.
