PVA103 charge amplifier module
The module is a general-purpose measurement and testing application, suitable for ordinary experimental teaching and simple measurement. For scientific research, engineering, and research directions, it is recommended to refer to our VK10X series high-precision charge amplifiers.
Product application
*Dynamic force measurement *Object vibration
*Collision detection *Counter
Connection diagram of sensor and amplifier module
Definition of four core terminal of signal amplification module:
Power supply VCC+:+2.8~9V;
TTL: comparator output terminal; The comparison voltage is 0.6 * VCC
OUT+: output signal terminal;
GND: power ground/output ground
Definition of two core terminals of signal amplification module:
IN+: connected to the positive end of PVDF sensor;
GND: connected to the negative terminal of PVDF sensor;
(If PVDF is not connected to other circuits or other ground wires, the two terminals IN+and GND can exchange wiring at will).
