Use of low noise read-out - IC. For higher gain a regulation of bias voltage due to the temperature is to be realized. For very small signals stray light (noise source) is to be excluded by filters in order to improve the signal-noise relation. Avoid touching the window with fingers! Careful cleaning with Ethyl alcohol possible. Avoid use of pointed and scratching tools! min. 0,1 F, closest to APD APD Diode, protective circuit Read-out circuit or f.e. 50 Load resistance Handling precautions: * * * Soldering temperature min. Pin - length ESD - protection Storage 260C for max. 10 s. The device must be protected against solder flux vapour! 2mm Only small danger for the device. Standard precautionary measures are sufficient. Store devices in conductive foam. 2000/05 * |
