Photosensor amplifier C9051 Small on-board type current-to-voltage conversion amp The C9051 is a current-to-voltage conversion amplifier specifically designed for low-light-level measurement using a photodiode (sold separately). Features Applications Small on-board type for easy assembly Low-light-level detection Usable with photodiodes having large terminal capacitance Low-light-level optical power meters DC light monitors Conversion impedance: 1.0 × 108 V/A Single +12 V supply voltage operation Small board size: 50 (W) × 50 (H) × 19 (D) mm Absolute maximum ratings (Ta=25 °C unless otherwise noted) Parameter Symbol Value Unit Maximum voltage Vcc max +16 V Operating temperature*1 Topr 0 to +50 °C Storage temperature*1 Tstg -10 to +60 °C *1: No dew condensation When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. www.hamamatsu.com 1 Photosensor amplifier C9051 Electrical and optical characteristics (Ta=25 °C, Vcc=+12 V) Parameter Conversion impedance Frequency bandwidth Input photocurrent range Maximum output amplitude Output offset voltage Equivalent noise input current Output noise voltage Symbol Tz fc Isc Vo Vos IN enp-p Condition C9051 board, -3 dB *2 RL=1 kΩ C9051 board Without photodiode, f=1 Hz Without photodiode, full bandwidth Min.

Photocurrent input from the photodiode will be negative with respect to the amplifier. *3: If not using the AC adapter that comes with the C9051, set the power supply voltage within this range. A separate adapter plug will be required for power input to the 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 the C9051, always make sure the power supply output does not contain excessive ripple and noise. Usable 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 datasheets for our photodiodes. Note: The C9051 cannot be used with multi-element photodiodes, photodiodes with preamplifier, APD (avalanche photodiodes), photo IC diodes and reverse-biased photodiodes.

(Keep the capacitance including the cable capacitance and photodiode’s terminal capacitance from exceeding 15 nF.) ・Solder the photodiode leads to connect the tip of the cable wire. (See the drawing on the right.) Anode: Connect to the shield wire of the cable. (Make electrical connection with the shield.) Cathode: Connect to the core wire of the cable. ・To improve measurement accuracy, provide a shield around the photodiode. Do not use a cable any longer than necessary. (Keep the cable as short as possible.) Coaxial cable with BNC plug Solder Photodiode Anode Note: When using a photodiode whose cathode is internally connected to its metal package, secure the photodiode with an insulating material when shielding. Otherwise, signal current cannot be drawn when the photodiode package is grounded.
