Application Notes—Photoconductive Cells

APPLICATION NOTE #7

How to Specify a Low Cost Photocell

Sometimes the demands of the application such as power dissipation,

“on” resistance, voltage, temperature coefficient, etc. limit the selection

of the photocell to one particular device. However, more common is the

case where any number of photocell types can be used, especially if

minor changes are undertaken at an early enough point in the circuit

design. In these cases, price is often the deciding factor.

Many factors influence price. In order to give some guidance and

weight to these factors the reader is referred to the following table

which is meant to serve as a general guide.
