Reader O f f er To win: three USB-based multifunction instrument packages This month’s reader offer consists of three USB-based instrument packages worth 360 Euros each, combining EasySYNC’s Stingray multifunction instrument (USB-based oscilloscope) with the company’s ES-DLA-16 lightweight single channel logic analyser, together with a pair of HP3060 oscilloscope probes. Measuring 116x30x100mm, the Stingray multifunction instrument (DS60M10) is powered from USB and needs no external power supply. It combines the functions of oscilloscope, data logger, spectrum analyser, frequency meter and voltage meter functions in a single instrument. With simultaneous 10/8-bit sampling on two channels and a native sampling rate of 60MHz for the oscilloscope, the unit also runs as a data logger up to 1K samples with sophisticated hardware triggering. The DS60M10 oscilloscope also has a 3rd channel which can be an external trigger input. The ES-DLA-16 single channel logic analyser combines the functions of RAW, Run Length Encoding, internal and external clock and 16 channels into one unit. Maximum sampling rate is 60MHz or 4-bit RAW with an external clock input. It features a search function, zoom in, zoom out and full view display. The unit comes complete with an attractive enclosure with rubberized mouldings, portable carry case, one USB cable and two testing cables/probes. The HP3060 oscilloscope probes feature an input bandwidth of 60MHz and come with a full set of clips and accessories. Input impedance is 1Mohm in x1 mode and 10Mohm in x10 mode. Check the reader offer online at www.electronics-eetimes.com MOSFET platform delivers integrated Schottky performance with low leakage current NXP Semiconductors N.V. has released the NextPowerS3 30-V MOSFET platform incorporating the company’s ‘SchottkyPlus’ technology. NextPowerS3 is the industry’s first MOSFET to deliver the high frequency, low spiking performance usually associated with MOSFETs with an integrated Schottky or Schottky-like diode but without problematic high leakage current. NextPowerS3 30 V is suitable for a variety of applications, including high efficiency power supplies for telecoms and cloud computing, high performance portable computing and batterypowered motor control, such as rechargeable power tools. The trend in recent years has been to create faster and faster switching MOSFETs in an effort to reduce switching losses and increase the efficiency of switch mode power supply (SMPS) designs. However, faster switching on its own can generate problems in terms of switch node voltage spikes, coupled gate glitches and the potential for shoot-through, raising EMI and reliability concerns. One popular solution has been to integrate Schottky and Schottky-like diodes into MOSFET structures. However, Schottky diodes introduce high leakage currents, especially at elevated temperatures, which impact efficiency, battery life and the ability to screen for defectivity in the manufacturing process. Combining super-fast switching with soft recovery, NXP’s NextPowerS3 range addresses each of these concerns, delivering increased efficiency and higher power density, while keeping voltage spikes under control and limiting leakage current to less than 1 μA. NXP Semiconductors N.V. www.nxp.com Gigabit-Ethernet board-level camera built around 5Mpixel Aptina CMOS sensor The IDS Gigabit-Ethernet board-level GigE uEye LE camera series is now also available with the high-resolution 5 Megapixel (2560x1920 pixels) CMOS sensor from Aptina. With its A-Pix technology the sensor offers an excellent image quality and enhanced sensitivity. Measuring only 45x45mm the GigE uEye LE is one of the most compact boardlevel Gigabit-Ethernet cameras in the market. What’s more, it can take a maximum cable length of up to 100 meters which makes it very useful in industrial applications. The cameras also offer easy integration due to trigger, flash, two general purpose I/Os and an I2C-Bus for controlling external devices. An internal image memory of 60MB enables the image acquisition and transfer to be decoupled. The GigE uEye LE is also available with either M12 lens holder for inexpensive S mount lenses or a CS lens mount. IDS Imaging Development Systems www.ids-imaging.de RGB/ambient light and proximity sensor IC supports wide dynamic range ZMD AG has launched the ZOPT3100, an RGB/ambient light and proximity sensor IC which integrates an ambient light sensor (ALS), a color sensor (CS), and a proximity sensor (PS), as well as an integrated IR LED driver on a single chip. It is optimized for enabling adjustment of brightness as well as color for display panels. With five integrated photodiodes (one for proximity and four for white, green, blue, and red channels), four high-resolution 18-bit analog-to-digital converters (ADCs) for optical signals and one 11-bit dual-slope ADC for proximity measurements, this IC enables parallel measurement of light and proximity. It reaches a wide dynamic range of 0.006 lux to 32,000 lux for ambient light sensing and provides linearized output results for color sensing via the red, green and blue channels. The IC’s simultaneous measurement of distance and ALS/CS is well suited to applications such as deactivating a touch screen during phone calls in mobile phones. Integrated filters help suppress 50/60Hz ambient light flicker. A wide supply voltage range of 2.4 to 3.6 V combined with a low supply current of 200 uA (excluding the LED driver) and a configurable standby mode allow its use in mobile batterydriven applications. The ZOPT3100 delivers high sensitivity especially in low-lux areas, making it optimal for usage behind dark cover glasses.
