PRODUCT SHOWCASE Freeview Plus TV upgrade Freeview Australia, a consortium of free-to-air TV stations, has delivered the new Freeview Plus service to more than 2.2 million Freeview Plus-enabled TVs across Australia. Freeview Plus is designed to make content discovery easier than ever before, offering a simplified user experience, additional features and a fresh look and feel. Freeview Plus is a hybrid digital television service that provides access to catch-up free-to-air programming on TVs and led the world when it launched in 2014, winning local and international accolades for its ground-breaking technology and user interface. There are currently around 2.2 million TV receivers in Australia that are Freeview Plus-enabled with an 85% Smartphone Temperature Datalogger connection rate. Key to the upgrade has been the implementation of world’s best practice interface design which now features image-based browsing and the introduction of the My TV function. My TV presents the viewer with image-based carousels including personalised recommendations and viewers’ favourites along with live TV, catch up and genre-based browsing. Other Freeview Plus upgrade features include an easy-to-use guide with backwards navigation to catch-up content and a simplified Mini Guide for quick program discovery. For more information, visit www. freeview.com.au or view the how-to video at siliconchip.com.au/l/aaem New record for LONGi 60-cell Solar Module: 325.6W LONGi Solar received a test report showing its latest 60 cell Hi-MO1 module achieved a power output of 325.6W under standard testing conditions (STC) with the conversion efficiency reaching 19.91%. The module incorporates monocrystalline PERC cells based on mass production technology with a 21.9% conversion efficiency. The test was completed at the Contact: TUV Rheinland Shanghai LERRI Solar Technology Co Ltd Lab with the open-circuit 201, Building 8 Sandhill Plaza, Lane 2290, Zuvoltage and short-circuit chongzhi Rd, Pudong, Shanghai, China current reaching 40.79V and Tel: (0011) 86 021 6104 7322 10.160A respectively. Website: http://en.longi-solar.com Rail-to-rail op amp with inbuilt EMI protection EMI – electromagnetic interference – is the bane of engineers and circuit designers everywhere. Among a host of problems, EMI causes DC errors, increased current consumption and unwanted tones. Now Microchip have introduced the MCP6411, a single, general purpose op amp offering integrated EMI protection and rail-to-rail input/output over the 1.7 to 5.5V operating range. This amplifier has a typical GBWP of 1 MHz, with typical quiescent current of 50µA. The MCP6411 is available in SC-70 and SOT-23 packages. 106  Silicon Chip Integrated EMI protection, when used with proper circuit/PCB design techniques, eliminates external components that increase system cost, design complexity and footprint. Many applications could benefit from integrated EMI protection, including medical instrumentation, automotive electronics, data acquisition equipment, battery powered portable systems, sensor amplification and conditioning and analog active filters. You can find the MCP6411 data sheet at siliconchip.com.au/l/aael Contact: Microchip Technology Inc Unit 32, 41 Rawson St, Epping NSW 2121 Tel: (02)9868 6733 Fax: (02) 9868 6755 Website: www.microchipdirect.com The new TagTemp-S, from Novus Automation, is a cost-effective data logger recommended for use in warehouse and transportation applications. It is an IP65 rated sealed unit with a temperature range of -30 to 60°C and can operate for 2 years at a 5-minute acquisition interval. It can store up to 4020 readings. The stored data is transferred through a smartphone equipped with an embedded NFC interface or by an NFC interface connected to a computer through a USB port (both not included). The LogChart-NFC smartphone app allows the user to configure the logger and view and graph the temperature history. The NOVUS Cloud Portal is offered as an optional service to TagTemp-NFC users. The LogChart-NFC Android app can be configured to send out temperature recordings read from TagTemp-NFC devices straight to the internet portal. Once stored on NOVUS Cloud, records can be checked from any internet browser. Prices start at $59.00 +GST each.
