PHOTO IC Photo IC for laser beam synchronous detection S9703-10/-11 High sensitivity, high-speed response S9703 series photo IC uses a high-speed PIN photodiode designed for laser beam synchronous detection. When compared to S9703 and 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 power to be used. Tape-and-reel shipment is available (S9703-30 and S9703-31). HAMAMATSU also provides S9684 series photo ICs that use a dualelement Si PIN photodiode.

The photodiode chip is internally connected to the IC chip as shown in the block diagram. S9703-10/-11 should be used with terminal Ro connected to an external gain resistance Ro. A photocurrent is generated when a laser beam enters the photodiode. This photocurrent is fed to the input terminal of the IC and, after being amplified by the current amplifier, flows to the external gain resistance. At this time, voltages VRO at terminal Ro is given by the following expression. VRO=A × S × PI × Ro [V] ·········· (1) A: Current amplifier gain (S9703-10: 20 times, S9703-11: 6 times) S: Photodiode sensitivity [A/W] (approx. 0.44 A/W at 780 nm) PI: Input power [W] Ro: External gain resistance [Ω]; usable range 2 kΩ to 10 kΩ VRO is input to the internal comparator and compared with the internal reference voltage Vref (approx. 1 V) so the output Vo is “High” when VRO < Vref or “Low” when VRO > Vref. In equation (1), set the Ro value so that VRO is 2 to 3 V. ■ Dimensional outline (unit: mm) 3.2 ± 0.2 (INCLUDING BURR) 0.66 ± 0.2 1.0 ± 0.4 1.0 ± 0.4 3.9 4.0 * 3.4 MIRROR AREA RANGE 3.8 4.0 * 0.8 0.8 0.8 0.8 3.0 * 4.2 ± 0.2 PHOTOSENSITIVE SURFACE 0.5 2.84 0.15 ± 0.2 (10 ×) 0.3 (10 ×) 0.4 CENTER OF ACTIVE AREA 0.05 0.35 5.0 ± 0.3 0.45 ± 0.3 3.0 * 2.8 0.1 ± 0.1 0.15 2.4 MIRROR AREA RANGE 2.9 3.0 * 0.75 0.45 ± 0.3 1.3 PHOTOSENSITIVE SURFACE Tolerance unless otherwise noted: ±0.1, ±2˚ Shaded area indicates burr.
