module photosensor amplifier digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise C9329 C9329 is a current-to-voltage conversion amplifier used to amplify very slight photocurrent from a photodiode with very low noi se. three ranges of photocurrent detection sensitivity level (h, m, l) are selectable to match the input signal. C9329 operates on the built-in dry batteries so it can be easily used anywhere. C9329 can be directly connected to a personal computer through the rs-232c interface allowing you to a cquire high- resolution (16-bit) digital output signals and use the data logger function. features applications l three sensitivity ranges h : 1 10 9 (v/a) m: 1 10 7 (v/a) l : 1 10 5 (v/a) l selectable operation modes (analog output / digital output) l serial connection (rs-232c) with pc l data logger function, low battery function l operates on either dry battery or ac adapter l precision photometry l laser monitors l optical power meters l low signal current preamplifiers 1 absolute maximum ratings (ta=25 c) parameter symbol value unit maximum supply voltage vcc max. +14 v operating temperature * 1 topr 0 to +50 c storage temperature * 1 tstg -10 to +60 c *1: no condensation electrical and optical characteristics (ta=25 c) parameter symbol condition min. typ. max. unit h - 1 10 9 - m - 1 10 7 - conversion impedance l rf -1 10 5 - v/a h 0 - 5 m 0 - 500 input photo current range l ic 0 - 50000 na hdc16- m dc 1.6 k - frequency bandwidth (-3 db) l fc dc 1.6 k - hz offset drift - *2 - - 0.5 mv/day temperature drift - - - 25 v/ c maximum output amplitude v fs r l =2 k ? 5 - - v output noise vn frequency bandwidth * 3 - - 0.5 mv p-p output resistance ro - 100 - ? maximum input capacitance ct overshoot 30 % max. - - 5000 pf analog output (manual mode) maximum capacitive load c l - - 1000 pf interface - rs-232c, 19200 bps, 8-bit, non-parity, 2-stop bit - a/d conversion voltage range - 5 v digital output (remote mode) a/d read cycle - - 50 - ms consumption current is * 4 - - 20 ma battery lifetime - r l > 10 k ? * 4 -50-hr *2 without photodiode. maximum output variation per day, measured at 25 c after 10-minute warm-up after power on. *3 analog output measured after amplified 10 times (through 1.6 khz low-pass filter). *4 without photodiode. when using one alkaline dry battery 6lr61 (006p, 9 v) in analog output.
photosensor amplifier C9329 this is an example using a photodiode whose cathode is internally connected to its metal package. when you use a photodiode metal package, use an insu- lator to electrically insulate and also hold the package in a shield case as shown in the figure at right. connect the anode to the shield case. any single-element photodiode with a terminal capaci- tance below 5000 pf can be used. using a photodiode with anode grounded is recom- mended. using a photodiode with a bnc connector (s2281 se- ries) allows you to easily make measurements because it connects to C9329 with a bnc-bnc plug coaxial cable. kaccc0221ea typical connection to photodiode 2 anode: connect to the shield wire of the cable and shield case. cathode: connect to the core wire of the cable. solder insulator cathode anode photodiode external shield case coaxial cable with bnc plug connect to C9329 terminal connection example operation example by digital output (remote mode) coaxial cable with bnc-bnc plug photodiode (s2281 series) to rs-232c terminal pc to in terminal to dc terminal ac adapter (need not be connected when operating on battery) switch C9329 rear sw to "remote mode" rs-232c cable rf range switch kaccc0222ea display example of accessory sample software data logger setting range measurement interval: 50 ms to 1 min (50 ms interval) measurement count: 32000 max. measurement interval meassurement count: 20 hours max. dimensional outline (unit: mm, excluding project parts) accessories ~ ac adapter (plug type: a-2 plug) * 5 ~ dry battery ~ sample software cd-rom (os: windows98se/me/2000/xp * 6 ~ instruction manual *5: caution) depending on the country, an adapter plug might be required when connecting to the ac outlet. if so, please purchase a proper adapter plug from an electronics supply house. *6: resistered trademark of microsoft corporation in the united states. photodiode, coaxial cable with bnc-bnc plug and rs-232c cable are not supplied with C9329. you will need an rs-232c cable (straight cable terminated with a d-sub 9 pin female connector at both ends) available from electronics supply houses. kacca0137ea upper surface rear manual mode dc jack dc12v eiaj rs232c only for remote modes remote mode out in 90 ?1 115 ?1 40 ?1 front rf range h m l zero adj. data log. photosensor amplifier C9329 power on auto zero push start note: use the rf range switch to change the detection sensitivity.
