Product Summary
The LSBC847BLT1G is a 8-channel active photosensor array. The LSBC847BLT1G 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 of the LSBC847BLT1G 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 of the LSBC847BLT1G avoids a ground referenced signal and permits the subsequent electronics to adjust the gain. In its simplest form this is done by load resistor.
