The JTIA1-1G transimpedance amplifier from ifw optronics amplifies the photocurrents generated by SiC UV photodiodes, which are only a few nanoamperes strong, and converts them into a usable voltage level. The user can select from the following three preconfigured resistance values via jumpers: 10 MOhm, 100 MOhm, and 1,000 MOhm. Depending on the setting, the photocurrent is amplified in a ratio between 1 V/nA and 0.1 V/μA. In addition, the output voltage can be amplified by a factor between 1× and 11× via a trimming potentiometer. This value is freely selectable.
The component, which is available from LASER COMPONENTS, is particularly user friendly. Photodiodes in TO5 or TO18 housings can be connected directly to the board. Since the JTIY1-1G supports numerous application possibilities, users do not have to develop their own circuit boards to use their SiC UV photodiodes as quickly as possible.
