Using the Stellaris Serial Flash Loader (AN01242)
Texas InstrumentsThis application note describes how to communicate with the Stellaris serial flash loader application.
Dual Output Boost Converter
Texas InstrumentsThe boost converter is modified to provide bipolar 12-V outputs from 5-V supply. Using the UCC3803 to control the basic boost converter building block the -12-V outputs are generated using a coupled inductor and a flying capacitor. Output voltage regulation and efficiencies are compared and presented.

ADSL Clear EOC Channel Capability
Texas InstrumentsThis application report outlines the implementation of a CPE remote management scheme using the clear EOC Channel. The capabilities of the Clear EOC Channel are discussed for G.dmt different framing mode as well as ADSL2. This application report is meant to be used to provide a basic understanding of the Clear EOC channel and how it might be used for ADSL CPE remote management.
Using Feature Set of I2C on TM4C129x Microcontrollers
Texas InstrumentsThe inter-integrated circuit (I2C) is a multi-master multi-slave single-ended bus that is typically used forattaching lower speed peripheral ICs to processors and microcontrollers. The type of slave devices range from non-volatile memory to data-acquisition devices like analog-to-digital converters (ADC) sensors and so forth. This application report demonstrates how to use the feature rich I
Serial ROM Boot
Texas InstrumentsWith ever increasing speeds of DSP devices such as the 'C5x and the increasing demand for reduced form factors as in HDD applications there is a need for integrating the program memory into the DSP device. For volume production where the program code has been fully debugged and changes are not foreseen then masked ROM is appropriate. However for prototyping and preproduction evaluation a p

Texas InstrumentsThis application note discusses the operation and compensation of linear regulators.
Delta-Sigma ADC Design for Bridge Sensor Applications
Texas InstrumentsThis application report reviews several different types of bridge sensors including characteristics of each type and discusses the key parameters of delta-sigma (ΔΣ) analog-to-digital converters (ADCs) at the system level. Additionally the parameters of a ΔΣ ADC are considered for use in common bridge sensor applications
Nine-Axis Sensor Fusion Using Direction Cosine Matrix Algorithm on MSP430F5xx (Rev. A)
Texas InstrumentsThis application report explains the implementation of an Attitude and Heading Reference System (AHRS) using the ultra-low-power MSP430F5xx microcontroller a magnetometer a gyroscope and an accelerometer on all three axes. The calibration of the sensors is key to the accuracy of the algorithm therefore the sensors’ output must be calibrated before being input to the Direction Cosine Matrix (

A Low Noise, Low Distortion Design for Antialiasing and Anti-Imaging Filters
Texas InstrumentsIn any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from "folding back" around the sample frequency and causing false (or alias) signals from app
Using the TMS320VC5510 Bootloader (Rev. C)
Texas InstrumentsThis document describes the features of the on-chip bootloader provided with the TMS320VC5510 Digital Signal Processor (DSP). Included are descriptions of each of the available boot modes and any interfacing requirements associated with them instructions on generating the boot table and information on migration from the prototype (TMX320VC5510 revision 1.x) to the production (TMS320VC5510) boot
Battery Charger Termination Issues With System Load Applied Across Battery
Texas InstrumentsBattery charger ICs base their full charge termination on either peak voltage detect (PVD/-dV) for nickel chemistries (bq2000, bq2002, and bq2004) or current taper for Li-ion batteries (bq24010, bq240
Predictive Gate Drive Boosts Converter Efficiency
Texas InstrumentsPredictive Gate Drive™ is a novel digital control-driven technique that optimizes MOSFET turn-on and turn-off delays in synchronous rectifiers. It uses a closed loop feedback system to detect body-diode conduction and continuously adjusts dead-time delays to minimize the conduction time interval. Depending upon operating frequency and output voltage the Predictive Gate Drive™ control
