The PDA200C Photodiode Amplifier is ideally suited for ultra low noise amplification of very small photodiode currents. It offers six current ranges from 100 nA to 10 mA full scale and provides a maximum display resolution of 10 pA. The unit supports cathode grounded (CG) and anode grounded (AG) photodiodes. This amplifier may be operated in either photovoltaic or photoconductive mode. The adjustable bias voltage provides improved linearity of the responsivity and increased frequency response.
With the updated PDA200C Series, our Photocurrent Amplifier is RoHS compliant. Additionally, the current measurement ranges were changed. The rest of the features are virtually the same as the former PDA200 Series.
