ADL5317-EVAL開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

ADL5317-EVAL屬于開發(fā)板套件編程器的評估演示板及套件。由亞德諾半導體技術有限公司制造生產的ADL5317-EVAL評估和演示板及套件該系列產品提供了一種方便的方法，在經過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產品系列。

GENERAL DESCRIPTION

The ADL5317 is a high voltage, wide dynamic range, biasing and current monitoring device optimized for use with avalanche photodiodes. When used with a stable high voltage supply (up to 80 V), the bias voltage at the VAPD pin can be varied from 6 V to 75 V using the 3 V-compatible VSET pin. The current sourced from the VAPD pin over a range of 5 nA to 5 mA is accurately mirrored with an attenuation of 5 and sourced from the IPDM monitor output. In a typical application, the monitor output drives a current input logarithmic amplifier to produce an output representing the optical power incident upon the photodiode. The photodiode anode can be connected to a high speed transimpedance amplifier for the extraction of the data stream.
