The CMOS ADS574 and ADS774 are drop-in replacements for industry standard ADC574 analog-to-digital converter offering lower power and the capability to operate from a single +5V supply. The switched capacitor array architecture (CDAC) with the input resistor divider network to provide ADC574 input ranges also allow the new parts to handle additional input ranges including a 0V to 5V range. Thi

This document describes filter design from the standpoint of cost. Filter design techniques that require the fewest possible op amps and passive components are described. Six types of filters are described - low pass high pass narrow bandpass wide bandpass notch and band reject.

This application note contains diagrams of the pin equivalent circuits for each of the pins in the bq76920, bq76930, and bq76940 devices.

This application report provides an overview of the technology and tools, and their applicability for the fastest turnaround time for your embedded system.

This document describes the functionality of the TMS320C6452 ROM bootloader software. The ROM bootloader resides in the ROM of the device beginning at ROM address 0x00100000. The ROM boot loader (RBL) implements methods for booting in the listed modes. It reads the contents of the BOOTCFG register to determine boot mode and performs appropriate commands to effect boot of device. If an improper boo

The paper presents an efficient method of teaching the Texas Instruments (TI(TM)) TMS320C3x digital signal processor (DSP) in the frame of a non-dedicated technical subject matter during an academic semester. Individual tasks are defined with similar difficulties and almost the same level of learning and understanding the processor capabilities. Some projects are presented as examples of the me

This application note describes how to communicate with the bq76940 family devices over I2C. The code is based on the TI MSP430G2553. The code shows how to write the CRC function which is used to verify the transaction integrity over the I2C and how to initialize the I2C engine of the G2553 and bq76940 registers as well as how to read binary data from the AFE registers and transfer the data to vol

This document provides board-level guidelines and techniques for designing with the TLC320AD50. This includes topics such as printed-circuit board construction power-supply decoupling noise reduction and general design guidelines. The intent is to provide strategies to help users attain first-pass design sucess with the TLC320AD50.

This application note describes the theory and operation of an analog gain scaling circuit that is required to obtain specified audio performance from the PCM1804.

The Texas Instruments (TI) TMS320VC5420 DSP implements limited boundary scan capability with respect to standard IEEE 1149.1 boundary scan devices. This application report contains a description of the 'VC5420 boundary scan implementation and information about how to use it with other boundary scan tools and devices.

This document serves as an overview describing the use of the Timer_A UART library within an existing C or assembly project. The Timer_A UART library encapsulates commonly used routines for transmitting and receiving bytes using UART. These functions are written in assembly to be optimized for the MSP430 but can be called from any C program that includes the ta_uart.h header file.

Differential gain (DG) and differential phase (DP) are two specifications that designers of composite videosystems use everyday. We will define them here just to be sure we are all speaking the same languageand to ensure understanding of the rationale of the test technique used by Texas Instruments.

The LM3492 demonstration board included in this package is designed for converting nominal 12VAC from electronic transformer output to drive seven series connected LEDs at 360mA average current. The

This application report describes the general requirements for initialization of the TVP5020 NTSC/PAL video decoder. The covered topics include hardware reset microcode download microcode file format conversion register initialization and register write/read latency issues.

The first priority for a photosensing application is to design good stability into the transimpedance amplifier circuit. The Texas Instruments developers of WEBENCH® designer tools have conscientiously provided photosensing designs with stable 60° phase margins, or an approximate 8.7% overshoot from a step-input signal.

WEBENCH Designer tools have powerful software algorithms and visual interfaces that deliver complete power, lighting, and sensing applications in seconds. This enables the user to make value-based comparisons at a system and supply-chain level before a design is committed. One tool among others embedded in the WEBENCH environment is the photodiode portion of Sensor Designer. This article is specifically about the WEBENCH Sensor Designer’s built-in photodiode circuit stability.

This application report describes the architecture and function of the 14-bit analog-to-digital converter (ADC) of the MSP430 family. The principles of the ADC are explained and software examples are given. The report also explains the function of all hardware registers in the ADC. The References section at the end of the report lists related application reports in the MSP430 14-bit ADC series.
