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)
