The iC-LSB sensor array, coming with 8 independent channels, is a general purpose optoelectronic scanner made to suit a variety of encoding applications, such as rotary and linear encoders used for motion control, robotics, power tools etc.
The sensor array features monolithically integrated photosensors with active areas of 800 µm x 300 µm each in combination with fast on-chip photocurrent ampliﬁers, enabling an analog output at reasonable signal strength to the circuit board.
The highside current source output construction avoids a ground referenced signal and permits the subsequent electronics to adjust the gain. In its simplest form this is done by load resistors, for instance.
The spectral sensitivity range includes visible to near infrared light, with the maximum sensitivity being close to a wavelength of 700 nm.
Output currents of up to 50 µA are supplied under low light conditions, for instance when illuminated at only by an 850 nm LED. The photocurrent gain3 µW/mm2 is 46 dB typically.
