The first in a family of new high-performance LLC controllers, TI’s new UCC256301 inductor-inductor-capacitor (LLC) resonant controller enables standby power of less than 40 mW when fully regulating the system output, while also performing better than industry efficiency requirements. By delivering the fastest transient response plus robust fault-protection features such as zero current switching avoidance, […]
Analog-to-digital converters (ADCs) need a reference voltage (VREF) input in order to operate properly. ADCs convert analog inputs that can vary from zero volts on up to a maximum voltage level that is called the reference voltage. The reference voltage determines the ceiling of what the ADC can convert, and is essentially the yardstick against […]
Texas Instruments introduced DesignDRIVE Fast Current Loop software that makes C2000 microcontrollers (MCUs) the first devices to push current-loop performance to less than 1 microsecond. Together, TI’s C2000 MCU portfolio and DesignDRIVE software delivers system-on-chip (SOC) functionality which simplifies drive control system development. New DesignDRIVE Fast Current Loop software outperforms traditional microcontroller (MCU)-based current-loop solutions […]
Texas Instruments (TI) introduced an analog-to-digital converter (ADC) and phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO) that deliver the widest bandwidth, lowest phase noise and highest dynamic range in the industry. The wideband ADC12DJ3200 is the fastest 12-bit ADC, delivering speeds up to 6.4 GSPS. The LMX2594 is the industry’s first wideband […]
A number of systems I have developed have required the processing of pulsed analog signals. Depending on the system, one or more attributes of the signal needed to be preserved and measured such as pulse height, pulse width, pulse shape and pulse position in time. Also, you usually need some gain to boost the signal […]
Chest-mounted electronics do a more accurate job of counting heart beats than do optical sensors on the wrist. That’s one of the conclusions to come out of a close look at this sport watch aimed at runners. Leland Teschler Executive Editor A sport watch from Garmin called the Forerunner 220 is basically a runner’s watch […]

The 16-bit digital-to-analog converter DAC8775 operates from a single, wide 12- to 36-V power rail, leveraging an integrated buck/boost converter to generate all of the required internal power supplies. Devised by Texas Instruments, the four-channel DAC8775 addresses the trend in factory automation and process control equipment toward input/output (I/O) modules that must squeeze more channels […]

Here’s how a 3D EM simulation can be used to accurately gage gate-driver trace inductance. JOHN RICE | TEXAS INSTRUMENTS INC. HIGH ELECTRON MOBILITY TRANSISTORS (HEMTS) were first introduced in the early 1980s and are touted for their exceptional switching qualities. These so-called heterojunction, field effect transistors (FETs) were originally developed for high-frequency RF power […]
Newark element14 is now shipping three new products in the successful open source BeagleBone range. The ever popular BeagleBone Black and element 14 BeagleBone Black Industrial are now joined by BeagleBone Black Wireless, the element14 Wireless Connectivity Cape and the element14 4.3” Display Cape. The BeagleBone® Black Wireless now has Wi-Fi and Bluetooth capabilities built […]
