Application Notes—Photoconductive Cells
APPLICATION NOTE #7
HowtoSpecifyaLowCost Photocell
Sometimes the demands of the application such as power dissipation,
“on” resistance, voltage, temperature coefficient, etc. limt 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
mnor 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.
