If the input voltage to a TPS249X controlled system is reversed, The TPS249X will be destroyed and the load will be exposed to the reverse voltage. This app note proposes a solution for both. A sche
This reference design takes into account the voltage current and start-up requirements of the TMS320F280x Digital Signal Processor (DSP) families. The operating input voltage ranges from 3.4 V to 6 V. This design is a high-efficiency solution that provides two voltage rails (1.8-V core supply and 3.3-V I/O supply) and an active-low reset signal to the DSP. This design can be easily adapted to fi
During various occasions a digital amplifier can generate a click or a pop. The click is generated at changes of the operational modes of the amplifier e.g. charging ofcapacitors or mute/unmute. For Class D amplifier systems click is typically at PWM start and stop. The audibility of a click depends on the system amplifier and speaker. Also perception of the click is subjective. This
This document describes the FlatLinkE point-to-point data-transmission interface that provides better than a two-to-one reduction in the number of signal lines used for synchronous parallel data-bus structures.
The run-time support library (RTS) supplied with each TI DSP C/C++ compiler provides C language I/O (CIO) in the form of the high-level functions such as fopen and printf and the low-level functions such as open and write which use device drivers to complete CIO requests. The RTS provides a way for the user to define a new device driver. This provides an easy way to use the sophisticated bufferi
This application report discusses a circuit that can be used when a light-emitting diode is required to indicate that a port is on that is powered in a TPS2384 system.
The TMS470 family of ARM7 microcontrollers has up to five I2C ports available depending on which device is selected. The TMS470 I2C engine is very flexible and powerful. This document describes how to read and write I2C data and how to select the I2C clock rate.
This report presents two methods of sine-wave generation. The first method is a fast direct table lookup scheme suitable for applications where speech is critical. The second approach an enhancement of the first includes linear interpolation to provide higher accurate waveforms.
A small monitor program for the MSP430F1xx and MSP430F4xx microcontrollers that incorporate at least one integrated USART provides a facility for examining the device memory and updating the flash con
MSP430™ microcontroller based capacitive touch buttons can offer increased performance when properly optimized and tuned for their specific application. Performance benefits that result from but
This application report contrasts and compares the characteristics and capabilities of voltage and current feedback operational amplifiers. The report also points out the many similarities between the two versions.
This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (ΔΣ) successive approximation register (SAR) and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document the product data sheet for a particular product specification is the best and final reference.
Texas Instruments (TI) Quad Flatpack No-lead (QFN) 14/16/20-terminal Pb-free plastic packages meet dimensions specified in JEDEC standard MO-241 allow for board miniaturization and hold several advantages over traditional SOIC SSOP TSSOP and TVSOP packages. The packages are physically smaller have a smaller routing area improved thermal performance and improved electrical parasitics while
This application report enables the easy incorporation of the MSP430AFE2xx family of MCUs featuring the SD24_A module as well as the MSP430i20xx family of MCUs which features the SD24 module into new designs. It covers programming system and peripheral considerations when creating firmware. The intent is to highlight a few key differences between the two families and how to incorporate each
