S9684

Photo IC for laser beam synchronous detection S9684 series S11282-01DS High-sensitivity and high-speed photo IC for high precision printing The S9684 series and S11282-01DS photo IC use a dual-element Si PIN photodiode and compare the two signals to obtain a highly stable output even when laser power or ambient temperature fluctuates. The current amplifier is available with two gain levels (6 times and 20 times) according to laser power to be used. The S11282-01DS operates at a low voltage (3.3 V) compatible with low-voltage peripheral components. HAMAMATSU also provides single-element Si PIN photodiode types (S10317 series). Features Photo IC for precision printing High sensitivity Current amplifier gain: 20 times (S9684, S11282-01DS) 6 times (S9684-01) Digital output Small package Suitable for lead-free solder reflow Photosensitive area (PD1: 2.5 × 0.3 mm, PD2: 2.5 × 0.5 mm) Low voltage (3.3 V) operation (S11282-01DS) Applications Print start timing detection for laser pri...
