With 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

Negative Buck Switching Regulator (using LM258x)

The switch-mode power supply primary current is often sensed using a power resistor. Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. T

This application note discusses the operation and compensation of linear regulators.

This 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

This 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 (

AN071 -- CC2430 to CC2530 Migration Guide

In 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

This 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 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™ 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

This application report demonstrates an effective method to interface the ADS1251 and ADS1252 sigma-delta data converters to the MSP430F449 microcontroller. The software for this application report wa

This application report presents a hardware solution for interfacing the TLV1572 10-bit 1.25 MSPS (Mega Samples Per Second) successive low-power analog-to-digital converter (ADC) to the TMS320C203 16-bit fixed-point digital signal processor (DSP). In addition a C-callable interface program is shown which supports the data transfer between ADC and DSP.

Customers can program ten EEPROM registers to optimize the ability of the bq26500/bq26501 to monitor the battery capacity of a given group or type of Li-ion pack cells. This document explains how to obtain the values to be programmed in EEPROM by using information known by the pack/system designers and manufacturers and data collected from packs.
