The MAX3963s dynamic range is optimized for use in multimode LED-based applications.The preamplifier converts a small photodiode current to a differential voltage, with typical transimpedance of 2K.Input-referred noise of only 21nA allows detection of signal as small as 267nA, while pulse-width distor。</p><p>2、外文翻译（原文）PLC QuestionABSTRACT: This paper describes the main components of the PLC, and attention problems in use (such as the environment in use, the use of pre-note, etc.)Central Processing Unit (CPU) is the brain of a PLC controller. CPU itself is usually one of the microcontrollers. Aforetime these were 8-bit microcontrollers such as 8051, and now these are 16-and 32-bit microcontrollers. Unspoken rule is that youll find mostly Hitachi and Fujicu microcontrollers in PLC controllers by。</p>
