Infineon is claiming a first: AEC-Q103 qualification for a MEMS microphone. It is the IM67D130A, which operates over -40°C to +105°C and has an acoustic overload point (AOP) of 130dB SPL which “allows the microphone to capture distortion-free audio signals in loud environments. Because of that, it can be placed inside or outside of the vehicle”, said the company. It “is ...

Panasonic is aiming at indoor air quality monitoring with a particulate matter sensor based on laser scattering. “SN-GCJA5 features an innovative optical sensor assembly to provide reliable operation over a long lifetime while accurately detecting particles as small as 0.3µm,” according to Farnell, which is stocking the sensor. It has an “optimised air pathway structure that minimises dust accumulation making ...

Chelmsford-based Teledyne e2v’s Space Imaging group has confirmed a contract with Leonardo to supply specialised image sensors and detectors. It will be part of the recently announced proposal of the European Space Agency’s (ESA) industrial policy committee to place six Copernicus Sentinel satellite missions in space. Specifically, Teledyne e2v will be supplying Leonardo with a space grade VNIR-SWIR detector unit ...

ams is establishing an imaging centre of excellence for consumer image sensors and product validation to support key US customers from the Riverwood Tech Campus in Rochester, New York, USA. A concentration of photonics expertise in research and development in the Rochester area means that there is a talent base to develop optical imaging. The Rochester location is in the ...

Murata has announced an inertial sensor for adding navigation to industrial equipment, even in environments where there is high mechanical shock and vibration. The six-degrees-of-freedom sensor is called SCHA63T and includes X, Y and Z-axis angular rate sensors and a three-axis accelerometer based on capacitive MEMS. Signal processing is done with two mixed signal ASICs that provide angular rate via an ...

Allegro is aiming at automotive bridge-type pressure sensors with an interface IC designed to connect directly to a strain gauge or other Wheatstone bridge sensor. Qualification is automotive AEC-Q100 Grade 0. Called A17700, it amplifies and offset-adjusts the analogue input to best-fill the ADC for its internal digital signal processor. DSP includes filtering to trade speed with noise, then compensation for pressure ...

The National University of Singapore and Politecnico di Torino teamed up at ISSCC 2021 to describe a capacitive sensor interface designed to run from harvested energy, needing only a supply voltage between 300mV and 1.8V to produce an output accurate to seven bits, and consuming 1.4nJ per conversion. Not only that, but it needs no trimming, reference voltage nor supply ...

Microchip has introduced some high-side automotive current sense amplifiers, claiming that they have the lowest offset for AEC-Q100 Grade 0 qualified parts. Called MCP6C02, the Grade 0 part comes in a 3 x 3mm 8 pin VDFN package with wettable flank plating and has a maximum offset error of ±12µV, while the 6pin SOT-23 version is AEC-Q100 Grade 1. This max ...

ST is aiming at compliant 3 phase watt meters with an evaluation kit built around the STPMS2 double channel 24bit second-order ΣΔ modulator. Called EVALSTPM-3PHISO, it measures through a voltage divider and current shunt for each phase. “Sensing circuitry and PCB layout are optimised to maximise signal-to-noise ratio for accuracy,” said the company. The STPMS2 oversamples signals using a 4MHz clock ...

On Semiconductor has released a pcb-level low-frame-rate low-power IoT smart camera for cloud-based AI image capture and recognition. Called the RSL10 Smart Shot Camera, it is intended to add “the power of [cloud] AI-based image recognition to low-power IoT endpoints, such as surveillance cameras, restricted areas, factory automation, smart agriculture and smart homes”, according to the company. “A companion smartphone application ...
