productroundup 2.1-MHz class-D amp for automotive audio designs Texas Instruments presents this four-channel amplifier as delivering high-resolution audio quality in the smallest footprint. The first 2.1- MHz Class-D audio amplifier specifically designed for automotive applications supports high-resolution 96-kHz digital input. The TAS6424- Q1 enables the use of smaller external filters and eliminates up to 18 external components ompared to existing Class-D solutions. With maximum output power of 75W per channel, the device features the highest-available switching rate and is the only audio amplifier that switches above the Complete AM band. article, here Newly published; “EMC for Product Designers” Now in its 5th edition, this text shows how to incorporate EMC principles in product design, avoiding cost and performance penalties to meet the needs of specific EMC compliance standards. A specific addition covers issues around functional safety. The book aims to present a complete introduction to EMC for product design,written by a practising consultant in the field. It includes short case studies that demonstrate how EMC product design is put into practice; and it provides the latest 2016 mandatory regulations of both the RTTE Directive and EMC Directive. SPI/I²C micromodule isolator has 2x 5V regulators LTM2887 is a 6-channel SPI/Digital or I²C μModule (“micromodule””) isolator with dual rail regulated power that targets low voltage components, including newer DSPs and microprocessors. No external components are required. A single 3.3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC. Two regulated adjustable supply rails (up to 5V) deliver more than 100 mA over the isolation barrier, with up to 62% efficiency. The voltages may be adjusted as low as 0.6V for the auxiliary supply, while the isolated logic supply may be as low as Complete 1.8V for SPI interfaces. article, here Resistive RAM EEPROM improves embedded-system security Adesto Technologies (Santa Calara, California) is a maker of resistive-RAM memory. The company’s Mavriq DS memory is presented as an ultra low power EEPROM device family that is able to provide improved IoT security, with high levels of write endurance and hack-resistant one-time programmable (OTP) security registers. The Mavriq ‘DS’ (Digital Security) Series claims low-power operation, excellent endurance and features to enable better security in IoT and other connected devices. It performs read and write operations with 4x less power than competitive solutions, and, in ultra-deep power down mode, uses as much as 50x less power. DS devices can automatically enter the ultra-deep power-down mode following write operations, reducing controller operations and overall system energy. The new products also provide users over 100,000 write cycle endurance across the full temperature and voltage range.
