Active analog filters can be found in almost every electronic circuit. Audio systems use filters for frequency-band limiting and equalization. Designers of communication systems use filters for tuning specific frequencies and eliminating others. To attenuate high-frequency signals, every data acquisition system has either an anti-aliasing (low-pass) filter before the analog-to-digital converter (ADC) or an anti-imaging (low-pass) filter after the digital-to-analog converter (DAC). This analog filtering can also remove higher-frequency noise superimposed on the signal before it reaches the ADC or after it leaves the DAC. If an input signal to an ADC is beyond half of the converter’s sampling frequency, the magnitude of that signal is converted reliably; but the frequency is modified as it aliases back into the digital output.

Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. Young students may just know of TI as producers of their world famous graphing calculators. However, for the older, more experienced students, they quickly learn TI has technology that can be found everywhere. In fact, many of the ICs used for basic electronics are all created by TI.
There is also one additional area TI’s technology excels at. That would be in energy efficient electronics. One of the more popular devices is the MSP 430 microcontroller family. These MCUs allow developers to create embedded applications, which can manage power extremely efficient. The CPU can work with speeds up to 25 MHz or can be lowered to save power in applications. More importantly, the MCU has a low power idle mode. When working in this mode the CPU will draw as little as 1 micro-Amp of current. Along with the low power capabilities, this MCU can also work with all the usual embedded electronics communication protocols and peripherals.

Texas Instruments Incorporated is offering developers a solution to the challenges posed by the Internet of Things (IoT) revolution with the company’s introduction of the SimpleLink Wi-Fi CC3000 module.
The IoT enables devices to be wirelessly connected to the home network and to the cloud. However, headless devices with no keypads or touchscreens including garage door openers, home appliances, lights, thermostats and treadmills can be complicated to connect to a Wi-Fi network.
The self-contained SimpleLink Wi-Fi CC3000 module features the SmartConfig technology, a Wi-Fi configuration process developed by TI that allows multiple in-home devices without displays to connect to a Wi-Fi network via a smartphone or tablet – in just one easy step.

Texas Instruments has developed a new, free real-time operating system (RTOS) based on a pre-emptive multithreading kernel, which will run on the full portfolio of TI microcontrollers, including dual core devices. TI-RTOS includes a deterministic, real-time multitasking kernel (SYS/BIOS) with a TCP/IP stack, including network applications, USB, EMAC, MMC/SD host and device stacks and class drivers, FAT-compatible file system fully integrated with C RTS file I/O functions and Ethernet, USB, UART, I²C and SD device drivers. It also supports low overhead core-to-core communication mechanism for dual-core devices. [via]

element14 has teamed up with top suppliers, including Texas Instruments, Wurth Elektroniks and Cadsoft, to launch a new wireless power microsite. Designed to accelerate the integration of wireless power solutions in popular applications, such as smart phones, digital cameras and more, the site gives engineers access to a wide range of technical experts, complimentary webinars, product roadtests, and safety and compliance standards.
Engineers are invited to learn more by registering for a free webinar – “Charging Innovation – Cut the Cord” – on Thursday, Sept. 20 at 3 p.m. GMT/9 a.m. CDT. Attendees will see a demo of the new microsite, an overview of wireless power reference designs, and an opportunity to have questions answered during a live Q&A session following the webinar.

The TPS22966 is a small, ultra-low RON, dual channel load switch with controlled turn on. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.8V to 5.5V and can support a maximum continuous current of 6A per channel. Each switch is independently controlled by an on/off input (ON1 and ON2), which is capable of interfacing directly with low-voltage control signals. In TPS22966, a 220-Ω on-chip load resistor is added for quick output discharge when switch is turned off.

Texas Instruments has announced the introduction of the PowerLab Reference Design Library, a collection of power management reference designs. The reference designs include relevant technical documentation, such as circuit schematics, printed circuit board layouts, lists of components and materials, Gerber files, and other design support tools.
The library holds more than 300 power management reference designs for a variety of both isolated and non-isolated power conversion topologies suitable for lighting, telecommunication, computing and consumer electronics applications.
An interactive search tool is available on the website and new designs will be added to the database each month. [via]

Here is Texas Instrument’s application note on Ball Grid Array IC packages - [via]
Leaders in the consumer electronics industry will be determined by their ability to deliver increasingly miniaturized products at lower costs. The Ball Grid Array (BGA) package achieves these objectives by providing increased functionality for the same package size while being compatible with existing Surface Mount Technology (SMT) infrastructure.
