To perform correct measurements on a true digital audio amplifier (TDAA) it is important to understnad the characteristics of the device especially in comparison with conventional linear amplifiers such as Class-A and Class-AB. This report provides an overview of TI's proprietary digital amplification technology and information about how measurements on TDAA's must be performed in order to obtai

The purpose of this document is to describe the steps / process required to correctly build and test Linux NFC (neard) on AM335x (Cortex-A8) based BeagleBone + BeagleBone RF Cape + TRF7970ATB connecte

The bq27x00 is an accurate coulomb counter and contains algorithms to dynamically compensate the available capacity for temperature and discharge rate. If direct drive from the gauge to an LED display is not required the bq27x00 can be used as an accurate gas gauge solution for a primary cell battery. Although the bq27x00 was designed for a single-cell rechargeable lithium-ion or lithium-polymer

DSP/BIOS II is a kernel that provides run-time services which developers use to build DSP applications and manage application resources. DSP/BIOS II effectively extends the DSP instruction set with real-time run-time kernel services that form the underlying architecture or infra-structure of real-time DSP applications.The DSP/BIOS II kernel tightly integrates with the Code Composer Studio (

Current Mode Modeling - Reference Guide

Sensing the inductor DCR voltage can be an accurate and lossless technique of obtaining current information in DC/DC regulators. The absence of a series current sense resistor permits high current and high efficiency designs at a lower cost and higher density. Inductor DCR sensing also allows continuous monitoring of the inductor current as opposed to MOSFET RDS(ON) sensing that usually samples th

The AIC111 is an ultralow-power fixed sample rate sigma-delta codec with a sample rate of 40 kHz and a usable bandwidth of 10 kHz. Typically most applications process data at sample rates of 8 kHz 16 kHz and 20 kHz. This requires that the DSP or microprocessor connected to the AIC111 decimate the incoming data from 40 kHz down to the required sampling frequency and interpolate the data back

Differences between MSP430F67xx and MSP430F67xxA Devices

Texas Instruments has introduced a family of high-speed analog-to-digital converters (ADCs) suited tomeet the demand for high-speed and high-IF sampling systems. To achieve the highest overall system performance an analog front-end circuit with an antialiasing filter must drive the ADC with the highestpossible dynamic range and lowest distortions. One important parameter of the front-end circ

Understanding and Eliminating EMI in Microcontroller Applications

This application report describes how to access the extended memory in devices with memory greater than 64 KB using the large code/small data model supported by the IAR C/C++ compiler v3.42A and Code

PowerPAD ? A Method to Create Thermally Enhanced Plastic Package Solutions for Semiconductors

The software demonstrates a g.729a voice codec running on the DM642 EVM. The demonstration collects stereo samples and plays back the resulting samples. The right channel samples are not modified and fed straight through. The left channel samples are fed through a g.729a encoding and decoding process and the resulting samples are played back.

The demonstration uses/features:

• Low pass

Advanced F021 Flash Erase/Program Support

This application report demonstrates how TI?s DS42MB100, DS40MB200, and DS42BR400 equalize XAUI backplane FR4 traces and reduce data dependent jitter to within XAUI specifications.

The TPS61040 is a highly integrated low-power boost converter capable of delivering output voltages up to 28 V. Additionally using a coupled inductor enables the TPS61040 to be used in applications where higher voltages are required - up to 75 V can be achieved.

The TMS320DM6446 device can be configured as a universal serial bus (USB) host or slave device. When configured as a host it can support USB mass storage devices such as USB flash drives which are widely used today to transfer pictures music and documents between PCs laptops and portable devices; however this support is not enabled by default. This document outlines the necessary steps for e
