Product Information

Lock-in Amplifier/Preamplifier
Low Noise DC Power Supply

Our Experience and Know-How Made Sure the Amplifier Was Packed with the Advantages of DSP.

LP5393 and LP5394 are low noise DC power supplies with an output noise voltage of 10 µVrms or less. Not only the circuit technology but also the shield structure inside the power supply enables the same level of low noise as a battery.

The LP series achieves not only low noise output, but also excellent temperature stability compared to general DC power supplies. It is suitable as a power supply for electric circuit which measures small signals that is usually affected by noise and voltage stability. Therefore it can be used as a DC power supply for a low noise preamplifier.
