Resistive

电源供应器与数字电位器校准应用笔记

Abstract: A Resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solves the problem of adjusting a power supply. For easier automatic calibration, a mechanical pot can be replaced witha digital pot. This application note presents a calibration solution that uses a digital pot, because digipots are smaller, do not movewith age or vibration, and can be recalibrated remotely. This proposed solution reduces the susceptibility of the system to thetolerance of the digital pot's end-to-end resistance, making the solution optimal fordesigners. This application note also explainssome of the equations required to calculate the resistor chain values and to use a digital pot in this way. A spreadsheet withstandard reisistor values is available for easy calculations.

利用MSP430扫描接口使用GMR传感器

该应用报告描述了旋转检测器的实现，该旋转检测器使用一对可检测磁场的巨磁阻GMR（Giant Magneto-Resistive,）传感器。传感器的分布使它们不使用正交信号序列，这提供了讨论非正交情况如何配置SIF的机会。讨论了调试SIF应用程序的技术，提供了一个设计非正交进程状态机（processing state machines）的工具。

The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a Resistive ladder and capacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.
