With operating frequencies exceeding 300MHz Texas Instruments line of monolithic and hybrid currentfeedback operational amplifiers have become an attractive option for the RF (and IF) design engineer.Typical operational amplifier specifications do not however include many of the common specificationsfamiliar to RF engineers. To help the designer exploit the many advantages these amplifier
Portable electronics with long battery lives are unquestionably more marketable. Power consumption of the microprocessor can be reduced by lowering the internal clock frequency and/or even more by lowering the core supply voltage. Dynamic voltage scaling (DVS) is used to reduce core supply voltage to minimize power consumption. This application note explains how to implement DVS using a TPS6220
IEEE Std 1394b-2002 specification allows the use of optical media for longer distances at higher speeds. The use of optical media provides galvanic isolation lower electromagnetic interference (EMI) and lower interference from the environment.Interfacing 1394.b physical-layer devices (PHYs) may require additional components depending on the type of fiber-optic transceiver (FOT) selected. Th
The bq2000 charger can be used to charge Li-Ion, NiCd, or NiMH batteries. It uses three charging modes, the pre-charge, fast charge, and termination mode. It detects the battery chemistry type during
This document discusses how to use the C programming language to control the AIC on the TMS320C5x EVM. Different ways of doing this are shown with code listings and examples for each.
DSP/BIOS and the Reference Frameworks allow developers to non-intrusively instrument real-time applications. The software provided with this application note applies real-time analysis (RTA) services to a working application--?a H.263 encode/decode loopback example for the TMS320DM642 evaluation module.

The LaunchPad™ ACTBP host application is the firmware running on the MSP430 LaunchPad development kit to demonstrate the Audio Player Recorder Framework for the C5000™ Audio Capacitive Touch BoosterPack.
A Memory Protection Unit (MPU) is a module used to modify the memory types and attributes as defined in a processor?s memory ordering model. The MPU is specific to each core in the system and can only
The ADS1202 is a precision 80dB dynamic range delta-sigma (ΔΣ) modulator operating from a single +5V supply. The differential inputs are ideal for direct connections to transducers or low-level signals. With the appropriate digital filter and modulator rate the device can be used to achieve 15-bit analog-to-digital conversion with no missing codes. This application note describes ho
Power-on-Ethernet is an emerging technology that allows an existing Ethernet connection to carry both data and power. However today's powered-device (PD) designers face a dilemma - not all Ethernet connections are wired for power. To operate with these legacy connections a PD can use a wall adapter but this capability must be designed into the PD.

This application brief describes a 3-axis acceleration data collection system that uses a TLV2772 operational amplifier to amplify and filter sensor electrical signals. Use of the available evaluation
The thermal management of printed-circuit boards is complex but must be well understood to achieve optimum performance and reliability. SWIFT(TM) dc/dc converters in the 28-pin HTSSOP package rely on an exposed lead frame die pad [PowerPAD(TM)] on the bottom of the package to provide an extremely low thermal resistance from junction to case. The thermal performance of the 6- 9- and 14-A SWIFT d
