Using the Capture Units for Low Speed Velocity Estimation on a TMS320C240
Texas InstrumentsEstimating velocity from a digital position sensor is a cost-effective strategy in motor control. Equations are given for two different first order approximations for velocity. This document describes how the capture units are used for low speed velocity estimation on the TMS320C240. Equations are given to demonstrate the techniques used. There is a lengthy code example and timing diagrams to show

Using IBIS Models for Timing Analysis (Rev. A)
Texas InstrumentsToday?s high-speed interfaces require strict timings and accurate system design. To achieve the necessary timings for a given system input/output buffer information specification (IBIS) models must be used. These models accurately represent the device drivers under various process conditions. Board characteristics such as impedance loading length number of nodes etc. affect how the device d
Digital Audio Measurements
Texas InstrumentsTo 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
Build Instructions for neard (Linux NFC) for AM335x + TRF7970A
Texas InstrumentsThe 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
Using the bq27x00 With a Primary Cell Battery
Texas InstrumentsThe 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 Technical Overview
Texas InstrumentsDSP/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 (
AN-2060 LM27402 Current Limit Application Circuits (Rev. A)
Texas InstrumentsSensing 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
Efficient Resampling Filters for the AIC111
Texas InstrumentsThe 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

Input Impedance Measurement Using ADC FFT Data
Texas InstrumentsTexas 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
