Toshiba has introduced four dual-channel 150Mbit/s digital isolators in 4.9  x 6 x 1.75mm surface-mount packaging. Options allow two channels in one direction, or one channel in each direction, and outputs that default high or low. They are: DCL520C00 2x forward, defaults low DCL520D00 2x forward, defaults high DCL521C00 1x forward, 1x reverse, defaults low DCL521D00 1x forward, 1x reverse, ...

Aiming at lithography, Texas Instruments has created a digital micromirror device (DLP) with 8.9 million pixels that update at 110Gpixel/s. “Mask-less digital lithography machines – which project light materials without a photomask or stencil – are becoming increasingly popular for the manufacturing advanced packaging [that] combines multiple chips and technologies into a single package,” according to the company. DLP991UUV, as ...

Nexperia has announced six-channel bi-directional multiplexers that work with analogue and digital signals across 1.08 to 3.63V and up to 500MHz. Maximum port-to-port skew is 500ps. Inside the part, called NMUX27518 (or NMUX27518-Q100 for the automotive version), there are six change-over switches controlled as two blocks of three by two control pads, plus an over-riding chip enable. The switches can ...

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 ...
