Texas Instruments has announced a 9 x 9mm controller IC for the DLP472TP 4K (3,840 x 2,160, UHD) digital micromirror device that it revealed recently. Describing the controller, DLPC8445, as “90% smaller than the previous generation”, the company said that it can be used in lifestyle and gaming projectors “that achieve sub-millisecond display latency, matching or exceeding the world’s most ...
Nanusens has demonstrated a mems digitally-tuneable capacitor for 5G and 6G RF front-ends, that is compatible with CMOS IC processing and can be integrated with circuitry. The Q-factor is above 100 at 1GHz, and the four-bit capacitor has a minimum capacitance of 450fF (30fF/capacitor) with them all off and tunes up to ~1pF – a capacitance ratio of 2.2 which ...
TDK has introduced a low-power digital output mems microphone for voice command and sound detection in IoT applications such as smart watches and augmented reality glasses. Called T5848, it has a I2S interface and an ‘acoustic activity detect’ (AAD) function with its own outputs. Vital statistics of its surface-mount bottom acoustic port package are 3.5 x 2.65 x 0.98mm. Three traditional ...
Novosense Microelectronics has created a pair of isolated digital input chips suitable for 24V industrial control applications that only need power on the output side. 4-channel NSI8604 (SSOP16 package) and 8-channel NSI8608 (SSOP20) provide input/output isolation when converting voltages in the range of -60V to 60V to logic signals. (The third digit is a capital ‘i’, not a numerical ‘1’). ...
Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...
Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED and photo-diode or photo-transistor within a conventional opto-isolator with an SiO2 barrier across which the a modulated version of the input signal is passed – probably magnetically (Electronics Weekly has requested clarification). The ...
HBK has added IO Link digital communication to a range of tension and compression force sensors. U9C sensors (pictured) measure tension and compression, and C9C sensors measure only compression. This article was republished with far more information here The sensors easing digital up-grades by having identical mechanical dimensions and threads to their analogue counterparts. “With a standardised interface to any ...
Texas Instruments has created a series of precision current monitors with digital outputs, for use across power rails from -100mV to +85V, at up to ±78.64A. In each case, an internal ΣΔ ADC measures current across an integrated sensing resistor, as well as voltage and temperature – communication with the host if via I2C. The ICs need a separate supply ...
Toshiba has introduced a series of multi-channel digital signal isolators that “ensuring stable high-speed digital communications even in the toughest factory floor environments”, it claims. They have 100kV/μs minimum common-mode transient immunity (1.5kV common-mode, 25°C), and carry data rates up to 150Mbit/s. Isolation is 5kV for 1 minute. Called the DCL54xx01 series, they are four-channel devices with different combinations of ...
‘The Book: A cover-to-cover exploration of the most powerful object of our time’ is a charming and fascinating Radio 4 series that played over the weekend in omnibus form. I loved every minute of it, although was jarred by its final line, which described books as ‘unrepentingly analogue’. But surely, they are digital, as there are 26ish letters plus punctuation ...
