Abstract: This application note describes a new generation of digital-input Class D audio amplifiers that achieve high PSRRperformance, comparable to traditional analog Class D amplifiers. More importantly, these digital-input Class D amplifiersprovide additional benefits of reduced power, complex ...

电路连接 由于数码管品种多样，还有共阴共阳的，下面我们使用一个数码管段码生成器（在文章结尾） 去解决不同数码管的问题： 本例作者利用手头现有的一位不知品牌的共阳数码管：型号D5611 A/B，在Eagle 找了一个 类似的型号SA56-11，引脚功能一样可以直接代换。所以下面电路图使用SA56-11 做引脚说明。 注意： 1. ...

A MEMS microphone IC is unique among Analog Devices, Inc., products in that its input is an acoustic pressure wave. For this reason, some specifications included in the data sheets for these parts may not be familiar, or familiar specifications may be applied in unfamiliar ways. This application not ...

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to ...

Abstract: This tutorial discusses methods for digitally adjusting the output voltage of a DC-DC converter. The digital adjustmentmethods are with a digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor.Each method is assessed and several DACs and ...

Abstract: This article discusses application circuits for Maxim force/sense digital-to-analog converters (DACs). Applications include:selectable fixed-gain DAC, programmable gain DAC, photodiode bias control, amperometric sensor control, digitally programmablecurrent source, Kelvin load sensing, t ...

Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler fail ...

  The LTC®1966 is a true RMS-to-DC converter that uses aDS computational technique to make it dramatically simplerto use, significantly more accurate, lower in powerconsumption and more flexible than conventional logantilogRMS-to-DC converters. The LTC1966 RMS-to-DCconverter has an inpu ...

  The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection ( ...
