LM231AN DATASHEET PDF

These tendencies are brought from the thermal effects on the blue chip wavelength and the conversion efficiency of phosphors. For example, allocation between pad and solder mask, incline, lack, and unbalance of solder amount are main quality factor of assembly. S3 S2 S1 Min. The data of this application note is made especially for giving some reference information about LMA characteristics, not for any warranty. Finally designer could recognize how degree LED junction temperature can rise-up from these steps. Use of state of the art silicone More information.

Thus, it provides all the inherent advantages of the voltage-to-frequency conversion techniques, and is easy to apply in all standard voltage-to-frequency converter appli- cations. And, the frequency from a battery powered voltage-to-frequency converter can be easily channeled through a simple photoisolator to provide isolation against high common mode levels.

The precision timer circuit has low bias cur- rents without degrading the quick response necessary for kHz voltage-to-frequency conversion.
