*2: When connecting a photodiode to C9051, the cathode should be connected to the IN terminal of C9051 and the anode
grounded. Photocurrent input from the photodiode will be negative with respect to the amplifier.
*3: If not using the AC adapter that comes with C9051, set the power supply voltage within this range. A separate adapter plug
will be required for power input to C9051.
*4: This is the maximum ripple allowed for the power supply when operated with all loads listed on the power supply specification
sheet, excluding switching noise that might appear superimposed on the ripple. When not using the AC adapter that comes
with C9051, always make sure that the power supply output does not contain excessive ripple and noise.
IUsable photodiodes
Any single-element photodiode with a terminal capacitance below 15 nF can be used.
In photometric applications requiring high accuracy, we recommend using metal package or ceramic package photodiodes.
For detailed information refer to individual data sheets for our photodiodes.
NOTE) C9051 cannot be used with multi-element photodiodes, photodiodes with preamplifier, APD (avalanche photodiodes),
photo IC diodes and reverse-biased photodiodes.
