FeaturesTransimpedance Amplifier Board

 Most applications of photodiodes, and especially those in the ultraviolet wavelength range, require special amplifiers because of the small photocurrents. 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.

Wide single supply voltage range 5.0 V ... 18.0 V with surge and polarity protection

Low power consumption (<50 mW @ 5 V)

Analogue transimpedance channel with:

 Adjustable gain in the range 105 … 107 V/A with fine tuning option

 Schmidt Trigger stage with adjustable switching point and adjustable Hysteresis

 LED for easy adjustment of the Schmidt Trigger

Current to Frequency converter with:

 2 measurement ranges giving high dynamic range

 Standard CMOS compatible digital output
