Implementing a Thermocouple Interface With ADC12_A
Texas InstrumentsThis application report shows how to implement a single-chip thermocouple interface. The thermocouple interfaces with the MSP430F5529’s integrated 12-bit analog/digital converter (ADC12_A) through an operational amplifier circuit. The MSP430 encodes the thermocouple readings into a digital value converts them to temperature and stores them in memory.

Limitations of Slew Rate on the REFIN Pin of the TPS54X72 Family
Texas InstrumentsTracking dc/dc converters must track a reference voltage. However the rate of change in the reference voltage that the output voltage can successfully track is limited. This application report presents a typical application circuit and the reasons for these limitations along with the waveforms showing circuit performance when the reference voltage slew rates are increased above the maximum.

HDQ Communication Basics (Rev. A)
Texas InstrumentsThis report compares the communication timing specifications for the different battery gas gauge and battery monitor products. It discusses some of the interface requirements necessary for robust HDQ communication such as the need for a break prior to each communication how to reliably read 16-bit dynamic values over the 8-bit bus and the need for some noise filtering on the HDQ line. It also

Vocoder Implementation Using TMS470 High-End Timer
Texas InstrumentsThe TMS470 family of ARM7 microcontrollers contains a RISC coprocessor referred to as the High-End Timer (HET). The HET can implement complex I/O operations independent from the CPU one of which is the capability to generate PWM signals. This application report describes using this PWM capability along with an open source voice algorithm called Speex to encode 8-bit voice messages without the n
4-Wire and 8-Wire Resistive Touch-Screen Controller Using the MSP430 (Rev. A)
Texas InstrumentsThis application report describes how to use an MSP4309(tm) microcontroller to drive and read a resistive touch screen. The hardware and software solutions provided enable the reading of user input th
Clock jitter analyzed in the time domain, Part 3
Texas InstrumentsPart 1 of this three-part article series focused on how to accurately estimate jitter from a clock source and combine it with the aperture jitter of an ADC. In Part 2, that combined jitter was used to calculate the ADC’s signal-to-noise ratio (SNR), which was then compared against actual measurements. This article, Part 3, shows how to further increase the SNR of the ADC by improving the ADC’s aperture jitter, with a focus on optimizing the slew rate of the clock signal.
