AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photo diode without filter (“clear”). The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The device can also be synchronized to external signals via pin GPIO. AS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array. Control and Spectral data access is implemented through a serial I²C interface. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm.

The TMF8801 is a true direct time-of-flight (ToF) sensor system in a single modular package which offers highly accurate depth accuracy detection through a sub-nanosecond light pulse and an antialiasing “stop-watch” method to measure round-trip time of pulse. It provides single zone detection of an object irrespective of the color, reflectivity and texture of the object. The single module with VCSEL emitter offers high dynamic range and detection sensing measurements from 2 – 250 cm distances. The device utilizes highly sensitive SPAD detection with fast compact time-to digital converters to make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight. A built-in histogram is featured to detect cover glass and reports an object distances operating with the highest SNR while compensating for dirt and smudges contaminants on a products cover glass to produce artifact free measurement. The histogram delivers dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters. Data output is through a 1.8V I²C fast-mode communications interface and an integrated micro controller is featured with all algorithms included on-chip with no need for external optics.

The AS6221 is a high accurate digital temperature sensor with an accuracy of up to ±0.09°C, which is ideal for healthcare applications, wearables and devices requiring high-performance thermal information. The AS6221, is a complete digital sensor system, requires no calibration or linearization. It provides measurement outputs via a standard I²C interface. The sensor supports eight I²C addresses avoiding bus conflicts in multi-sensor use cases. The ultra-small size of the sensor (WLCSP 1.5 mm x 1.0 mm) enables accurate body/skin temperature measurements in very small health and lifestyle monitoring products. In addition to the high accuracy and the small form factor, the AS6221 offers a very low power consumption, for example measuring with 4 samples/s, the current consumption is only 6 µA. The sensor has 4 different automatic acquisition modes and keeps the high accuracy over the full supply range from 1.71 to 3.6 V. An integrated alert functionality triggers an interrupt to the micro controller when a temperature threshold is exceeded. The temperature threshold for the alert function can be adjusted in a device register.The AS6221 production test setup is calibrated according NIST and the verification equipment is calibrated by an ISO/IEC-17025 accredited laboratory.。 More information about Longevity Program

This compact UV-C LED is part of the OSLON UV series. It allows a flexible design for any application which requires UV-C radiation.

The AS7331 is a low-power, low noise integrated UV sensor. The three separated UVA, UVB and UVC channels convert optical radiation signals via UV optimized photodiodes to a digital result and realize a continuous or triggered measurement. The irradiance responsivity can be adjusted via Gain, conversion time and internal clock frequency to effect sensitivity, full scale range and LSB. The by the AS7331 detected amount of radiation in the set Gain and conversion time configuration will be provided as digital counts by the AS7331. The AS7331 offers a range of 12 Gain steps by a factor of two for each step. The conversion time is internally controlled over a wide range of 15 steps by a factor of two for each step. With the input pin (SYN), the conversion time can be externally controlled to adapt the measurement to the given environment and time base.With its irradiance responsivity factor and conversion time, the AS7331 supports an overall huge dynamic range up to 3.43E+10 (resolution multiplied by gain range). It achieves an accuracy of up to 24-bit signal resolution (internal via I²C and shifter 16-bit), with an irradiance responsivity per count down to 2.38 nW/cm² at 64 ms integration time. Via an integrated divider, the 16-bit I²C output can be adjusted to the significant bits of interest.
