This application note is intended for system designers who require a hardware
implementation overview of the development board features such as the power supply, the
clock management, the reset control, the boot mode settings and the debug management. It
shows how to use the High-density and Medium-density STM32F10xxx product families and
describes the minimum hardware resources required to develop an STM32F10xxx
application.
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, complexity, noise, and system cost.
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 applications problems whichwere much less important in earlier data converters, where ±15V supplies and ±10Vinput ranges were the standard.
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. Later, we describe how toplace components and route signal traces to minimize problems with crosstalk. Finally, we move on toconsider power supply-currents and end by discussing how to extend what we have learned to circuits withmultiple mixed-signal ICs.
