Current amplifier PDA200C Series

benchtoplow-noise

Features Transimpedance Photocurrent Amplifier Extremely Low Noise Operation Over Entire Dynamic Range 5 Digit Display with up to 10 pA Resolution Supports Single Point Power Calibration Supports Both Photodiode Polarities (CG and AG) Adjustable Bias Voltage Offset Compensation for Input Amplifier and Photodiode Dark Current RoHS Compliant 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. This photodiode amplifier is compatible with all of Thorlabs' mounted photodiodes. Our SM05-threaded mounted photodiodes feature a female SMA connector; to convert to BNC either an adapter cable or electrical adapter may be used.
