ADS1258, ADS1258-EP, and ADS1158 SPI? Timeout Function
Texas InstrumentsThis application report describes the SPI timeout function of the ADS1258, ADS1258-EP, and ADS1158. The goal of this application report is to describe the SPI timeout function and operation.
Time Domain Jitter Measurement Consideration for Low-Noise Oscillators
Texas InstrumentsPhase Noise and Jitter are important metrics that describe the quality of a low-noise oscillator. Jitter is a time-domain representation of the timing accuracy of a signal and Phase Noise is the frequency domain representation of noise spectrum around the carrier tone. Equipment for measuring jitter in time-domain such as real-time oscilloscopes excel in their ability to directly measure period
A FET OR-ing Circuit For Fault Tolerant Power Systems
Texas InstrumentsFault-tolerant power systems commonly achieve redundancy by diode OR-ing the outputs of several power supply modules. The OR-ing circuit is inefficient if the diode forward voltage drop represents a significant percentage of the load voltage. In low-voltage applications a FET OR-ing circuit can be more efficient. This application note discusses the design and performance of a FET OR-ing circui
Interfacing the ADS8361 to the TMS320F2812 DSP
Texas InstrumentsThis application note presents several methods for interfacing the ADS8361 16-bit SAR analog-to-digital converter to the TMS320F2812DSP. The software developed for this application note uses both the McBSP and SPI port to highlight the flexible digital interface of the ADS8361. In an effort to reduce development time the source code for this application note can be found on the Texas Instrument
Interfacing the TLV2544/TLV2548 ADC to the TMS320C31 DSP
Texas InstrumentsThis application report presents a hardware and software solution for interfacing the TLV2544/TLV2548 12-bit, 200-ksps, 4/8-channel, low-power, serial, successive approximation register (SAR) analog-to-digital converters (ADCs) to the 32-bit floating point TMS320C3X digital signal processor (DSP) through the use of the TMS320C31 DSP starter kit (DSK).
A digital-to-analog converter (DAC) interface to the DSP is also presented here exclusively for the single-shot mode operation of the ADC, since the DAC is used to reconstruct the digital data from the ADC for verification purposes. The TLV5618A DAC is used for this report.
Switched Cap Circuits Provide Efficient and Functional White LED Drive (Rev. B)
Texas InstrumentsTexas Instruments has many solutions for driving LEDs including switched capacitor converters and inductive based switching regulators. This application report describes some different switched capacitor methods of driving white LEDs and the benefits of each. The main areas of concern for most designers of portable equipment are efficiency size cost functionality and LED current matching.
TPD12S015 PCB Layout Guidelines
Texas InstrumentsThe TPD12S015 is a multifunction ESD protection device targeting portable HDMI (High Definition Multimedia Interface) applications. This application note focuses on layout guidelines for using the TPD12S015 DSBGA (Die Sized Ball Grid Array) 28 ball package mapped to HDMI C-type and D-type connectors. This solution is geared toward the smallest possible board area. To meet that goal the TPD12S015
