It is well known to analog experts that you can use the positive and negative inputs of an operationalamplifier to make a high-impedance current source (current pump) using a conventional operationalamplifier (op amp). This basic circuit can put out both + and - output current (or zero current) into variousloads. The theory is simple. But the practical problems involved are not so simple or

This document describes how to configure Codec Engine-based audio/video applications on the DM6446 (DaVinci) for use in a system that has less than the 256 MB of DDR2 memory that the evaluation board provides. Specifically we present steps for shrinking memory requirements down to 64 MB but the principles apply to any amount of DDR2.

This voice-echo canceler implementation is based on a similar implementation using the TMS320C2x 16-bit fixed-point digital signal processor (DSP). This document shows the differences between the two applications and highlights specific TMS320C5x features that support a voice echo canceler. The appendix provides a schematic for a dual-telephone interface for the TMS320C51.

This application report discusses the power consumption of the Texas Instruments OMAP-L138.

This application note explains the basic operation of the two-switch Flyback-power stage, and clarifies benefits and design restrictions not present in traditional Flyback-topology. Power st

When using the I2C™ bus protocol the designer must ensure that the hardware complies with the I2C standard. This application report describes the I2C protocol and provides guidelines on debugging a missing acknowledgment selecting the pullup resistors or meeting the maximum capacitance load of an I2C bus. A conflict occurs if devices sharing the I2C bus have the same slave address. This

This report details the factors that influence achievable accuracy of the low frequency oscillator, specifically for real-time clock (RTC) applications. The intent of this application report is to pro

This document describes the basic structure and operation of the digital micromirror device (DMD) array.

This document covers the basic structure and operation of DMD devices. The DMD is a unique combination of opto-mechanical and electro-mechanical elements. The journey begins with understanding how one pixel works and building on that to encompass the entire array of pixels that comprise a DMD.
