Vishay has released a digital ambient light sensor in a 4.38 x 1.45 x 0.6mm package, with AEC-Q100 qualification for automotive use. VEML4031X00, as it will be known, has a visible light spectral sensitivity designed to match the human eye, and also includes an ambient infra-red sensor for light source differentiation. “With an ambient light range from 0 to 172 ...

Toshiba has introduced some 50Mbit/s four-channel automotive high-speed digital isolators for digital signals. It is the DCM34xx01 series, and it has been designed to typically provide 100kV/μs common-mode transient immunity, in electric vehicle on-board chargers and battery management systems. Depending on the exact part, there can be: Four forward channels Three forward and one reverse Two forward and two reverse ...

Toshiba is aiming at UART and SPI interfaces with three four-channel dual-supply level-translator-transceivers. “The bus transceivers support level-up and level-down voltage translation from either of their dual power supplies in bidirectional communication systems using signal voltages between 0.8V and 3.6V,” said Toshiba. “These devices have been designed without any restrictions on the on-off sequencing of power supply terminals Vcca and ...

Pico Technology has added 16 digital channels to its 500MHz 3418E display-less USB oscilloscope, creating a model named ‘3418E MSO’. “MSO models offer engineers the ability to simultaneously capture and analyse both analogue and digital signals, perfect for mixed-signal designs such as microcontroller or FPGA-based systems,” according to the company. Minimum detectable pulse width on the digital channels is 5ns, ...

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 ...
