Maxim is aiming at medical wearables with a set of chips for sensing various vital signs. In particular, its chips are aimed at wearables that meets US Fedral Drug Administration (FDA) sensing specifications – so far, said Maxim, no wearables have achieved FDA approval. MAX86141 is an autonomous dual-channel (for two photodiodes) optical pulse oximeter plus heart rate sensor, measuring ...
A 9ns minimum on-time has allowed Rohm to offer a 60Vto 2.5V dc-dc converter – a 24:1 step-down ratio – that runs at 2MHz, claiming this to be a world first.Worst case minimum on-time is 20ns. Called BD9V100MUF-C, the BiCDMOS chip includes output mosfets and is aimed at 48V automotive systems. 2MHz operation keeps it out of the 2MHz the ...
Rohm has introduced some automotive grade op-amps which it claims cut noise problems through three built-in RC filters for input, output and power supply, aiming them at electric and hybrid vehicles. “Greater digitalisation and application density in automotive systems exacerbate the problem of EMC, since each additional component constitutes a potential source of interference. This presents significant problems for sensors ...
Toshiba has announced a family of CMOS low drop-out (LDO) regulators. Called TCR4DG, they have an on-off control input and come in in fixed output voltages between 1.0 and 4.5V, at up to 420mA. Typical drop-out is 193mV (420mA, 3.3Vout). Low output noise voltage is claimed, and as befitting a Japanese company, the claim is backed up by figures: Vnoise ...
Nanusens says its CMOS nano-sensor technology has solved the problem of stiction in MEMS inertial sensors.
Vishay expands its surface-mount 'TMBS' trench MOS Barrier Schottky rectifiers with 10 1A and 2A devices
The SDT series of Schottky diodes from Diodes is claimed to deliver superior performance to planar-type ones.
Japanese gallium oxide power device start-up Flosfia has raised Y750m (£5m) in series B funding. The firm, a spin-out from the Kyoto University, is aiming to commercialise crystalline α-Ga2O3 (corundum/sapphire/ruby structure) in power transistors and Schottky diodes – with the intention of manufacturing 600V TO-220 diodes in 2018 to compete against silicon carbide power devices. Its second intellectual property is ...
ON Semiconductor has picked up two consumer semiconductor awards in the run up to CES 2017 which takes place in Las Vegas next month. The Consumer Technology Association (CTA) recognised On Semiconductor’s Ezairo 7150 SL audio processor for hearing aids along with its Smart Passive Sensor (SPS). Ezairo 7150 SL is described as “an open-programmable digital signal processing (DSP)-based hybrid, which enables wireless connectivity in hearing aids ...
IQD’s new analogue ASIC-based temperature-compensated crystal oscillator (TCXO) is tested using one frequency reading every two degrees centigrade over the full operating temperature range. “This, combined with a high order compensation circuit, delivers a frequency stability as tight as ±0.5ppm over -40 to +85°C,” said the firm. Called IQXT-274, it comes in a 3.2 x 2.5 x 1.1mm hermetically sealed ...
