... C interface, reducing power consumption to less than 1µA. The ISL29012 supports a hardware interrupt that remains asserted low until the host clears it through I Designed to operate on supplies from 2.5V to 3.3V, the ISL29012 is specified for operation over the -40°C to +85°C ambient temperature range. Ordering Information PART NUMBER TEMP. ...

... I C Interface There are eight (8) 8-bit registers available inside the ISL29012. The command and control registers define the operation of the device. The command and control registers do not change until the registers are overwritten. There are two 8-bit registers that set the high and low interrupt thresholds ...

... Calculating Lux The ISL29012’s output codes, DATA, are directly proportional to lux. α The proportionality constant α is determined by the Full Scale Range (FSR), and the n-bit ADC which is user defined in the command register. The proportionality constant can also be viewed as the resolution ...

... Integration time affects the measurement resolution. For better resolution, use a longer integration time. For short and fast conversions, use a shorter integration time. The ISL29012 offers user flexibility in the integration time to balance resolution, speed and noise rejection. Integration time can be set internally or externally and can be programmed in the command register 00(hex) Bit 5 ...

... Ambient Light Sensing Operation 32 0.125 The operation of ambient light sensing (ALS) within the ISL29012 utilizes two diodes; D1 and D2. The D1 diode is sensitive to both visible and IR light spectrum. The D2 diode is sensitive to IR spectrum. D1 and D2 spectrum response is shown in Figure 21. The diodes are measured sequentially and their outputs are converted with an ADC ...

... A thickness 1mm is recommended for a window lens design. The bigger the diameter of the window lens the wider the viewing angle is of the ISL29012. Table 14 shows the recommended dimensions of the optical window to ensure both 35° and 45° viewing angle. These dimensions are based on a window lens thickness of 1 ...
