Charge converter CC-20
Charge converters convert the high-impedance electric charge output signal of piezoelectric accelerometers into low-impedance voltage signals.
These are line drive pre-amplifiers that enable the sensor output signal to connect to the measuring devices. The price is much lower, compared with ordinary charge amplifiers.

- Because of the characteristics of the circuit of this product, the phase of the input signal is inverted and output.
- To obtain the maximum output voltage, the following formula must be satisfied.
I > Vmax × πf × (Cc × 1000 × 10-12) + 0.12 × 10-3
I : Constant current value
Vmax : Maximum output voltage (Vp-p)
f : frequency (Hz)
Cc : Output cable capacity (F)
