Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise The C9329-01 is a current-to-voltage conversion amplifier used to amplify very slight photocurrent from a photodiode with very low noise. Three ranges of photocurrent detection sensitivity level (H, M, L) are selectable to match the input signal. The C9329-01 operates on the built-in dry batteries so it can be easily used anywhere. The C9329-01 can be directly connected to a personal computer through the RS-232C interface allowing you to acquire high-resolution (16-bit) digital output signals and use the data logger function. T hree sensitivity ranges H : 1 × 109 (V/A) M: 1 × 107 (V/A) L : 1 × 105 (V/A) Precision photometry Laser monitors Optical power meters Selectable operation modes (analog output/digital output) Low signal current preamplifiers Serial connection (RS-232C) with PC Data logger function, low battery function Operates on either dry battery or stabilized DC power supply Absolute maximum ratings (Ta=25 °C unless otherwise noted) Parameter Supply voltage Supply current Operating temperature*1 Storage temperature*1 Symbol Vs max Iin max Topr Tstg When there is a temperature difference between a product and the surrounding area in high humidity environments, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. *2: When used with a dry battery, temperature will be +5 to +40 °C. Note: xceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product E within the absolute maximum ratings.
