Inline charge amplifier: Robust, secure and simple
Our charge amplifiers convice with their secure design and high quality. This product is designed for the integration into tools, existing measurement systems of third parties and laboratory applications.
This charge amplifier works on the principle of an electronic integrator. The capacitive negative feedback of a high-impedance operational amplifier converts positive and negative charge displacements into an analog voltage signal. A digital signal is used to switch between the operating modes "Operate" (ON) and "Reset" (OFF) by specifying a measurement window at D-In 1. The signal for pre-setting the measuring window is galvanically isolated from the charging electronics by an optocoupler.
