The photocurrents generated by photodiodes are often in the range of a few nanoamperes. To be able to evaluate them better and use them for desired applications, they must be amplified and converted into voltage. For SiC UV photodiodes in our range of products, we recommend the JTIA1-1G transimpedance amplifier from ifw optronics. The user-friendly amplifier board can be connected directly to the TO5 or TO18 housings of the photodiodes.
Customers can choose from three preconfigured values via jumpers for their measurements: 10 MOhm, 100 MOhm, and 1,000 MOhm. Accordingly, the photocurrent is amplified at a ratio between 1 V/nA and 0.1 V/μA. A trim potentiometer can be used to additionally amplify the output voltage by a factor between 1x and 11x.
This amplifier component supports numerous application possibilities in pre-series production and in the final product. This allows you to quickly use your SiC UV photodiodes without investing time and effort in developing your own PCB.
