This report provides an understanding of the terms and definitions of low dropout (LDO) voltage regulators and describes fundamental concepts including dropout voltage quiescent current standby current efficiency transient response line/load regulation power supply rejection output noise voltage accuracy and power dissipation. Each section includes an example to increase the understandab

Using a 16-bit fixed point DSP to implement an IIR filter results in a calculation overflow of the output signal. Scaling the input removes the overflow but causes a low output signal. Boosting the output signal requires the addition of an op amp to the hardware design. This document shows an IIR software implementation using the TMS320C54x that accommodates the overflow without additional hardw

Ultrasonic sensing utilizing Time Of Flight (TOF) measurement techniques can be used to monitor material purity/contamination levels and or to differentiate materials non-invasively. This technology has been utilized in the automotive consumer medical and food preparation markets worldwide. Ultrasonic (TOF) sensing can yield high accuracy with low power consumption for all of

Companding (compression and expansion) is a method commonly used in telephony applications to increase dynamic range while keeping the number of bits used for quantization constant. The compression is lossy but provides lower quantization error at small amplitude values than at larger values.Mu-law is a companding standard commonly used in the United States. It takes 14-bit data values and co

This application report describes the process of migrating an existing Code Composer v4.12 project to a Code Composer Studio? Integrated Development Environment (IDE) v2 project.

Many telecom and networking applications require that cards be inserted and extracted from a live backplane without interrupting data or damaging components. To achieve this interface terminals of the card must be electrically isolated from the bus system during insertion or extraction from the backplane. To facilitate this Texas Instruments provides bus-interface and logic devices with features

Integrated data acquisition systems can provide many benefits over discrete component designs. Superior performance power and cost savings along with shorter development times are among these benefits. Features such as integrated programmable gain amplifiers and averaging can provide added resolution. This application note includes information on how to achieve 17 bits of effective resolution

This article provides a well-reinforced procedure for the PCB layout task as it pertains to the TPA300x series of class D amplifiers. This information can also be used in the layout of the TPA200x ser

Designers are giving more attention to the electromagnetic compatibility of electronic circuits and systems. The electromagnetic properties of particular interest are the generation of the lowest or zero interference and the immunity of circuits to the effects of the electromagnetic energy it is subjected to. This document explains important criteria that determine the electromagnetic compatibilit

Compact disc (CD) media is used for storage of audio files because of its relatively inexpensive cost and its large capacity. Today people want to be able to play popular compressed audio files (MP3 WMA AAC etc.) with the same player that can play legacy audio CDs. In order to have skip-free playback these players need to provide protection from external shocks especially in the case of port
