VTL5C6

The VTL5C6 is an Analog Optical Isolator has been found to provide a very economical and technically superior solution for many applications. It consists of a light-tight package which houses a light source and one or more photoconductive cells. Through control of the input current or voltage applied to the AOI, the output resistance can be varied. The output resistance can be made to switch between an ON and OFF state or made to track the input signal in an analog manner. Because a small change in input signal can cause a large change in output resistance. This AOI is an axial vactrol and it has a large dynamic range, high dark resistance, a low temperature coefficient of resistance and a small light history memory. It is a shallow sloped device with good dynamic range and average temperature coefficient of resistance, speed of response and light history memory.
