Abstract: AC and DC motors in modern industrial systems are often controlled via programmable logic controllers (PLCs) where an industrial mechanical potentiometer controls the motor speed. The wiper of these potentiometers can become worn...

Abstract: This application note introduces the DS1847 and DS1848, dual digital temperature-controlled variable resistors, to the industrial controls market. By temperature compensating the resistors, the resistors can either remain at a sp...

Abstract: The DS1267 is a dual digital potentiometer with a serial "shift register" type interface. The shift register has an input pin where data is shifted in as well as an output pin which shifts data out of the last bit of the shift re...

Abstract: Operate a digital potentiometer without the use of a microcontroller. Manually increment up/down with a simple push-button circuit. Perfect for cost sensitive applications where manual controls are required to set a particular le...

Abstract: The DS1868 uses a dual digital potentiometer with a 3-wire (shift register) interface. This application note describes the logic and firmware required to interface the DS1868, as well as any other Dallas Semiconductor 3-wire devi...

Abstract: Some digital systems have control bits that are set to HI or LO depending on the configuration of the system. A common example in a PC is a configuration jumper or dipswitch that sets which disc drive is the master or slave on an...

Abstract: This circuit drives as many as four white LEDs in parallel from a 3.3V source, and adjusts the total LED current from 1mA to 106mA, in 64 steps of 1dB each. The circuit of Figure 1 is designed for portable-power...

摘要：本篇應用筆記討論了DS3900串口通信模塊和LabView的使用問題，LabView是適用于嵌入式應用的圖形化界面開發(fā)平臺。本文可作為面向DS3900的LabView界面用戶指南。 ...

摘要：在某些應用中，采用MAX999等高速比較器將輸入正弦信號轉換成方波，產(chǎn)生時鐘輸出，對于這些應用，了解所生成時鐘的抖動非常重要。本應用筆記回顧了抖動的基本理論，介...

Abstract: This application note covers the use of look-up tables in the control of laser bias and modulation. The tables are a part of a feedforward control based on temperature which varies the value of the controlling signal as temperatu...
