Charge Amplifier (6 Channel)

  • 1. High Input Impedance and Impedance Conversion: Provides extremely high input impedance (typically greater than 1e12 ohms), drawing almost no current from high-impedance signal sources and converting high-internal-resistance charge sources into low-internal-resistance voltage sources to meet the processing requirements of subsequent circuits.

    2. Elimination of Cable Capacitance Influence: Its operating principle ensures that measurement results are unaffected by changes in connecting cable length and distributed capacitance, guaranteeing measurement stability and accuracy.

    3. High Sensitivity and Wide Bandwidth: Capable of measuring very small charge signals (down to the femtocoulomb level) and has a wide operating frequency range, suitable for dynamic signal measurements from extremely low to high frequencies. Typical operating frequency band is 0.3Hz to 100kHz.

    4. Low Noise and Fast Response: Employs low-noise, low-drift precision operational amplifiers with high gain and fast response characteristics, ensuring signal clarity and timely response to input changes.
