ADSL Full Rate & G.Lite Central Office Modem, Analog Front End, Using TLV320AD12
Texas InstrumentsThis application note defines the system-level hardware for the asymmetrical digital-subscriber line (ADSL) central office analog front end (AFE) incorporating the Texas Instruments TLV320AD12 (AD12). The AFE design is intended to demonstrate the data-handling capabilities of the AD12 in a real system environment. This application notes uses a simple line-coupling network; the end user should consider enhancements for actual implementation.

Simple Filter Turns Square Waves into Sine Waves
Texas InstrumentsMany signals are digitally generated or transmitted as square waves. It is often desirable to convert these signals into sine waves. For example the 350Hz 440Hz 480Hz and 620Hz telephone supervisory tones transmitted over fiber-optics may appear at curb-side as square waves. To be used in telephone equipment it is desirable to convert the square waves into low-distortion sine waves. This can b

bq29330 External Short Circuit Protection
Texas InstrumentsIn Li-ion battery pack design short-circuit protection should be given sufficient emphasis to ensure that even if an external pack short does occur it is benign. Properly designed battery fuel gauge solutions using the bq29330 analog front-end (AFE) protector and bq20z70 bq20z75 bq20z90 and bq20z95 fuel gauge ICs not only safeguards the battery but also ensures a full recovery of functionali
LED Display System Module Using Cascading TLC5940 Devices
Texas InstrumentsDescribed in this document are application ideas and reference designs for the TLC5940 LED driver. The following application example shows the building of a basic module of an LED display system using a cascading connection on n TLC5940 devices connected to a controller. The reference design implements three TLC5940 devices to drive 16 LEDs.
TLV2370/71/72/73/74/75 EMI Immunity Performance
Texas InstrumentsThe electromagnetic interference (EMI) rejection ratio, or EMIRR, describes the EMI immunity of operational amplifiers. An adverse effect that is common to many op amps is a change in the offset voltage as a result of RF signal rectification. An op amp that is more efficient at rejecting this change in offset as a result of EMI has a higher EMIRR and is quantified by a decibel value.
How (Not) To Decouple High-Speed Operational Amplifiers
Texas InstrumentsDecoupling the power supply pins of high-speed operational amplifier circuits is critical to their operation. Decoupling is also one of the least understood topics in engineering. It is seldom given the time or care required yet it is relatively simple. This document will explain the pitfalls in decoupling and offer some correct techniques.
