PHOTO IC Photo IC for laser beam synchronous detection S9703 series High sensitivity, high-speed response S9703 series photo IC uses a single-element high-speed PIN photodiode designed for laser beam synchronous detection. The current amplifier is available with two gain levels (6 times and 20 times) according to laser power to be used. Hamamatsu also provides S9684 series photo IC that uses a dual-element Si PIN photodiode ideal for high precision printing. Features Applications l High sensitivity l Print start timing detection for laser printers, digital copiers, Current amplifier gain: 20 times (S9703) 6 times (S9703-01) l Digital output l Small package l Suitable for lead-free solder reflow l Active area: 2.84 × 0.5 mm fax machines, etc. ■ Absolute maximum ratings (Ta=25 °C) Parameter Symbol Supply voltage Vcc Power dissipation *1 P Output voltage *2 Vo Output current Io Ro terminal current IRO Operating temperature Topr Storage temperature Tstg *1: Derate power dissipation at a rate of -4 mW/°C above Ta=25 °C. *2: Vcc=+0.5 V or less Value -0.5 to +7 300 -0.5 to +7 5 3 -25 to +80 -40 to +85 Unit V mW V mA mA °C °C ■ Electrical and optical characteristics (Ta=25 °C, λ=780 nm, Vcc=5 V, Ro=5.1 kΩ, unless otherwise noted) Parameter Symbol Condition Min.

The photodiode chip is internally connected to the IC chip as shown in the block diagram. S9703 series 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] A: Current amplifier gain (S9703: 20 times, S9703-01: 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. We recommend using S9703 series under the operating conditions that VRO is 2 to 3 V. ■ Dimensional outline (unit: mm) 1.0 ± 0.4 1.0 ± 0.4 3.9 4.0 * 3.4 MIRROR AREA RANGE 3.8 4.2 ± 0.2 0.8 0.8 0.8 0.8 3.0 * 4.0 * PHOTOSENSITIVE SURFACE 0.5 2.84 (10 ×) 0.3 (10 ×) 0.4 0.15 (CENTER OF ACTIVE AREA) 3.2 ± 0.2 (INCLUDING BURR) 0.67 (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.
