模拟电子 D类数字输入放大器的简化系统设计
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 ...
模拟电子 传感器信号调节 - 用于信号调节的ADC
The trend in ADCs and DACs is toward higher speeds and higher resolutions atreduced power levels. Modern data converters generally operate on ±5V (dualsupply) or +5V (single supply). In fact, many new converters operate on a single +3Vsupply. This trend has created a number of design and ap ...
模拟电子 正确的混合信号设计印刷电路板(PCB)的接地
Abstract: This tutorial discusses proper printed-circuit board (PCB) grounding for mixed-signal designs. Formost applications a simple method without cuts in the ground plane allows for successful PCB layouts withthis kind of IC. We begin this document with the basics: where the current flows. Lat ...
模拟电子 如何设计升压转换器MAX17597峰值电流模式控制器
Abstract: This application note describes how to design boost converters using the MAX17597 peakcurrent-mode controller. Boost converters can be operated in discontinuous conduction mode (DCM) orcontinuous conduction mode (CCM). This operating mode can affect the component choices, stress levelin ...
模拟电子 音频数模转换器DAC抖动的灵敏度分析
Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequenc ...
