The world's first wafer-level sensor chip came out, or set off a revolution in spectrometer applications


Leading high-performance sensor solution and analog IC supplier Amers Semiconductor (ams
AG) announced the world's first cost-effective multi-channel spectral on-chip sensor solution, opening the way for next-generation spectrum analyzers for consumer and industrial applications.

Using 4.5 x
The 4.4mm small array package, the ultra low power AS7262 visible light sensor and the AS7263 near infrared sensor all provide six calibrated spectral channels. The competitive price advantage makes this new multi-channel spectral sensor open to the testing and use of consumer and real-world applications. Its main solutions include material and product certification, product quality and integrity, and material analysis of near-infrared spectroscopy (NIR) and visible spectroscopy.

Jean Francois, Marketing Director, Emerging Sensor Systems, Amers Semiconductor
Durix said: "The increasing integration of sensors into smartphones and tablets has created a new wave of mobile applications, AS7262
The introduction of the AS7263 has enabled the widespread use of chip-scale spectral analysis, revolutionizing the development of spectral sensing for industrial and consumer applications. The new spectral sensing solution greatly reduces the cost and solution size of spectral analysis, and is widely used in food safety, product certification, routine testing and other applications to help better protect people's health and living environment. ”

Multispectral sensors use new manufacturing techniques to make nano-optical interference filters adhere directly to CMOS silicon wafers with extreme precision. The sensor uses an interference filter technology that is extremely accurate and stable, independent of time and temperature, and is smaller and more cost effective than components commonly used in today's spectrum analysis instruments.

Integrated intelligent AS7262 six-channel visible light sensor through I2C
The UART interface provides a calibrated digital output. It measures the light intensities at six different wavelengths in the visible range: 450 nm, 500 nm, 550 nm, 570 nm, 600 nm and
650nm. AS7263 can detect infrared characteristics of the near-infrared spectra of 610 nm, 680 nm, 730 nm, 760 nm, 810 nm, and 860 nm. Both products contain one with
The electronic shutter of the LED driver circuit means that the device designer can accurately control the light source and spectral detection functions from a single chip.

The new multi-spectral sensor features small size and low power consumption, making it easy for measurement equipment OEMs to develop new products with these features. For example, cumbersome lab-level analytical equipment can now be replaced by convenient handheld devices. At the factory, samples produced today have to be sent from the production line to the laboratory for chemical analysis, and future quality inspections will be completed on the production line with a new compact, robust spectrum analyzer based on multispectral sensors.

The AS7262 and AS7263 are in volume production. Evaluation boards for AS7262 and AS7263 are available from Amway Semiconductor's ICdirect online store.
