AIC27 Example for the TMS320C5510 Prototype Board
Texas InstrumentsThis application report is intended to help demystify the AIC27 example program that comes with the TMS320C5510? prototype board. The example program is intended to display some of the audio capabilities of the C5510? prototype board. Because it performs all these actions through header files and macros however it may seem unclear as to what is actually going on. This document clarifies what is
Use Low-Impedance Bridges on 4-20mA Current Loop
Texas InstrumentsIf you need more transducer excitation current than is available on a standard 4-20mA 2-wire current loop consider a 3-wire transmitter. A 2-wire 4-20mA transmitter uses the same two wires for signal and power. Part of the 4mA minimum loop current is used to power the transmitter circuitry. The remaining current can be used for transducer excitation. In some applications even the entire 4mA is no
bq20z40/45/60/65 Printed-Circuit Board Layout Guide
Texas InstrumentsAttention to layout is critical to the success of any battery management circuit board. The mixture of high-current paths with an ultralow-current microcontroller creates the potential for design issues that can be challenging to solve. This application report presents guidelines to ensure a stable and well-performing project.

Noise Analysis for High Speed Op Amps (Rev. A)
Texas InstrumentsAs system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu

AN-336 Understanding Integrated Circuit Package Power Capabilities (Rev. A)
Texas InstrumentsThe short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter
Interfacing the TLV1544 Analog-to-Digital Converter to the TMS320C50 DSP (Rev. A)
Texas InstrumentsThis application report presents two hardware solutions for interfacing the TLV1544 10-bit low-power analog-to-digital converter (ADC) to the TMS320C50 16-bit fixed-point digital signal processor (DSP). The report describes the interface hardware and shows three C-callable software routines which support the data transfer. In addition it provides useful hints on the design of a typical system pow
