Features
 Most applications of photodiodes, and especially those
in the ultraviolet wavelength range, require special amplifiers because of the
small photocurrents. Although the uv sensors of the TW30xx series provide large
active areas you will still usually consider using an amplifier. To support
your application development we offer this completely new photodiode
transimpedance amplifier board. Based on our successful Multifunctional
2-Channel Amplifier Board (Multiboard) we've included
additional features: an analogue channel with adjustable Schmidt Trigger (ST)
and a Current-to-Frequency converter (CFC) channel. The CFC clearly simplifies
the integration of our photodiodes into digital and microprocessor designs.
