Diodes has created a piezoelectric sounder driver that can output 31Vp-p, supplied from only 1.8 to 5.5V. It secret is that PAM8907 has a built-in synchronous boost converter and a bridge-style output. 22Vp-p can also be selected at the output – there is a logic input which sets the boost converter to produce 11 or ...

Silanna Semiconductor has designed an active clamp fly-back controller to reduce the operational, no-load and stand-by power consumption chargers and adapters. Called SZ1131, it has an integrated clamp mosfet and a driver for an external fly-back mosfet. Efficiencies up to 95% across 90 – 265Vac input voltages and varying loads are possible, according to the ...

Sensirion has introduced three flow sensors for ventilators. All based on its SFM3xxx platform, they are intended for inspiratory applications at ambient pressure. SFM3119 (pictured) is a digital flow meter, the successor to its SFM3100. Flows of air, oxygen and air-oxygen mixtures between -10 and 240 slm are measured, and output in 16bit format updated at ...

Infineon is aiming at augmented reality glasses and automotive head-up displays with a MEMs-based optical scanner. The company is giving very little away beyond this, except to say that the “MEMS scanner chipset features a tilting mirror which lays the foundation for a new generation of laser beam scanner projectors”, and that the chipset is ...

Harvard and MIT researchers have teamed up to prototype a self-contained saliva-based diagnostic Covid test that can distinguish between variants in an hour and is “just as accurate as the PCR tests now used”, according to MIT. It is called ‘miSherlock’, for ‘minimally-instrumented Sherlock’, where Sherlock is a Crispr-based DNA/RNA test invented at Harvard’s Wyss Institute ...

Highland Technology has introduced a pulse generator suitable for driving LiNbO3 Mach-Zehnder and similar electro-optical devices. Called T130, output swing is adjustable from -500mV to -7V, ac coupled into 50Ω. “Unlike typical telecom class electro-optical modulator driver modules specified for balanced data operation, the T130 output can swing up to 7V relative to baseline and is capable ...
