Ideal for evaluating noise in DC power output and DC signals! Observing μV-order signals superimposed on a 40V DC signal.
The "Low Noise AC Amplifier" is suitable for noise evaluation of DC power output and DC signals in circuit board design. It is capable of amplifying and observing noise and small signals in the μV range superimposed on DC signals up to 40V (expandable). It adopts a unique circuit that balances low noise performance and input protection, allowing for a low noise amplifier that can handle large DC voltages. 【Features】 - Well-suited for noise evaluation of DC power output and DC signals in circuit board design - Capable of amplifying and observing noise and small signals in the μV range superimposed on DC signals up to 40V - Adopts a unique circuit that balances low noise performance and input protection - Can apply large DC voltages 【Application Examples】 - Output noise evaluation of DC-DC converters and power modules - Output noise evaluation of power supply equipment such as linear power supplies - Output noise evaluation of voltage amplifiers - Output noise evaluation of solar cells on a per-cell basis *For more details, please refer to the PDF materials or feel free to contact us.
