Brochure

We offer three variations for our dual-channel transimpedance amplifier. The first variation is a fixed gain model, where the gain is set from factory for those who know their specific application. The second allows for selection of four gain values by button switch (per channel), covering a range of possible gains. The third is user programmable, which allows for a variety of gains from 1-400 kV/A, and allows for integration within instrument control processes.
