photo ic photo ic for laser beam synchronous detection high sensitivity, high-speed response s9703-10/-11 s9703 series photo ic uses a high-speed pin photodiode designed for laser beam synchronous detection. when compared to s9703 an d s9703-01 previously marketed, s9703-10 and S9703-11 have reduced their reflection effects in the package. two types of current amplifiers are available with a gain of 6 times (S9703-11) and 20 times (s9703-10) that can be selected according to laser powe r to be used. tape-and-reel shipment is available (s9703-30 and s9703-31). hamamatsu also provides s9684 series photo ics that use a du al- element si pin photodiode. preliminary data apr. 2007 features l high sensitivity current amplifier gain: 20 times (s9703-10) 6 times (S9703-11) l digital output l small package l suitable for lead-free solder reflow l active area: 2.84 0.5 mm applications l print start timing detection for laser printers, digital copiers, fax machines, etc. 1 absolute maximum ratings (ta=25 c, unless otherwise noted) parameter symbol value unit supply voltage vcc -0.5 to +7 v power dissipation * 1 p 300 mw output voltage * 2 vo -0.5 to +7 v output current io 5 ma ro terminal current i ro 3ma operating temperature topr -25 to +80 c storage temperature tstg -40 to +85 c *1: power dissipation decreases at a rate of 4 mw/c above ta=25 c. *2: vcc=+0.5 v or less electrical and optical characteristics (ta=25 c, =780 nm, vcc=5 v, ro=5.1 k ? , unless otherwise noted) parameter symbol condition min. typ. max. unit current consumption icc no input - 0.9 1.5 ma high level output voltage v oh i oh =4 ma 4.6 - - v low level output voltage v ol i ol =4 ma * 3 --0.3v s9703-10 17 22 27 threshold input power S9703-11 p th 60 75 90 w s9703-10 - 100 200 h l propagation delay time S9703-11 t phl - 75 150 s9703-10 - 200 250 l h propagation delay time S9703-11 t plh - 150 200 ns rise time tr - 4 7 ns fall time tf p i =66 w (s9703-10) p i =225 w (S9703-11) duty ratio 1:1 c l =15 pf * 4 - 4 7 ns maximum input power p i max. - - p th 8 w *3: input power [p i ]=66 w (s9703-10), p i =225 w (S9703-11) 50 % input light intensity output 100 % 0 % 90 % 1.5 v 10 % t phl tf tr t plh kpicc0112ea
