In many applications it is desirable for the output of an amplifier to swing close to its power supply rails. Most amplifiers only guarantee an output swing of ±10V to ±12V when operating on standard ±15V power supplies. With the addition of four resistors and a pair of garden-variety transistors the INA105 or INA106 difference amplifiers can be modified to provide nearly a f
This application report addresses high-speed signals such as clock signals and their routing and gives designers a review of the important coherences. With some simple rules, electromagnetic interfere
The purpose of this design note is to show how the serial peripheral interface (SPI) must be configured to be able to communicate with the CC1100/CC1101/CC1150/CC2500/CC2550. It also shows how the status bytes should be interpreted and how SW reset is done over the SPI interface.
This document provides an overview of the scan-path linker (SPL) and the scan-path selector (SPS) used to implement IEEE 1149.1 boundary-scan test. It discusses the use of remote bus controller interfaces and partitioning IEEE 1149.1 designs that use the scan-path support devices. The SN74ACT8999 is used in a SPS design and the SN74ACT8997 is used in a SPL design.

Many memory-module manufacturers are turning to low-profile (1U) DIMM designs that significantly increase memory density in computer workstations and servers. The reduction in DIMM height consequently
This application report discusses the Sallen-Key architecture. The report gives a general overview and derivation of the transfer function followed by detailed discussions of low-pass and high-pass filters including design information and ideal and non-ideal operation. To illustrate the limitations of real circuits data on low-pass and high-pass filters using the Texas Instruments THS3001 is i
This document discusses the power consumption of the Texas Instruments TMS320C6418 digital signal processor (DSP). Power consumption on TMS320C64x™ devices is highly application-dependent. A spreadsheet is provided to model power consumption for the user's application. To get good results from the spreadsheet realistic usage parameters must be entered. The low-core voltage and other power d
This design idea provides a simple non-isolated AC/DC power supply for low power applications such assmart grid E-meter applications. The design uses a capacitive-dropper front-end combined with aLM46000 SIMPLE SWITCHER® buck regulator from Texas Instruments. The circuit provides 3.3 V at aminimum of 50 mA from a line supply of 90 VAC to 265 VAC. Theory of operation as well as designequa
