The bq2000/T are programmable monolithic ICs for fast-charge management of nickel cadmium nickel metal-hydride and lithium-ion batteries in single- or multichemistry applications. This application note discusses simple ways to select all necessary components to implement various switch-mode topologies. It also discusses how to configure the bq2000/T inputs to accomodate different appplication c

This application report describes of the EMI immunity performance of the TLC2272 and TLC2272-Q1 family of operational amplifier devices.

It's really all very simple—once you understand it. Then here's the inside story on noise for those of uswho haven't been designing low noise amplifiers for ten years.

SN75DP130 Implementation Guide: DP130 in a Sink

This document describes how the multichannel buffered serial ports (McBSPs) in the Texas Instruments TMS320C6000™ digital signal processor (DSP) are used to communicate to a single-rate Serial Telecom (ST)-BUS-compliant device.

The McBSP receives the framing signal clock and data from the ST-BUS™ device and processes them to generate internal frame syncs and clocks for correct data

Analog switches are extensively used for switching audio signals in battery-powered applications such as mobile phones. In any cases the switch is powered directly from the battery but it receives control signals from a lower voltage processor GPIO. For most analog switches this application condition leads to an excess supply current draw that catches system designers by surprise. This applica

Digital signal processing algorithms are loop intensive by nature which presents a set of choices for the programmer working with the Texas Instruments (TI)(tm) TMS320C6x digital signal processor (DSP). Loops are implemented on the C6x with a branch instruction. To maintain the determinism of operations within the C6x pipeline a branch and its five delay slots are non-interruptible. The C6x code

Delta Sigma PLLs Raise The Standard For Performance

This application note describes how to extend the functionality of the standard hardware UART available on Stellaris® microcontrollers by using the 9-bit UART add-on.

This application report describes the development of a sensorless brushless DC motor phase advance actuator system based on the Texas Instruments (TI)(tm) TMS320C50 digital signal processor (DSP) and TMS320C50 evaluation module (EVM). Results show that applying a direct digital control methodology to the problem of controlled phase advance in a brushless DC machine substantially increases the effe

The bq20z70/90 evaluation module (EVM) and its corresponding evaluation software provides a rich and effective environment for examining the bq20z70/90 - a new advanced battery gas gauge. This application report covers this EVM and software with an emphasis on how to use it and what to expect. EVM board connections are discussed in detail and helpful hints are offered. For the evaluation softwar

The DS40MB200 is a new signal conditioning mux/buffer in TI’s high-speed product portfolio. It enables redundancy and acts as a repeater in high-speed backplanes and cables. It features programmable pre-emphasis and fixed input equalization enabling error free data links to 4 Gbps. It can also be used as a signal conditioning driver to provide equalization to FR4 board traces as well as cables s
