... C interface, reducing power consumption to less than 1µA. The ISL29013 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 ISL29013 is specified for operation over the -40°C to +85°C ambient temperature range. Ordering Information PART NUMBER TEMP. ...

... I C Interface 2 C There are eight (8) 8-bit registers available inside the ISL29013. 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. There are four 8-bit data Read Only registers ...

... 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 ISL29013 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 ...

... 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 ISL29013. Table 14 shows the recommended dimensions of the optical window to ensure both 35° and 45° vie wing angle. These dimensions are based on a window lens thickness of 1 ...

... All dimensions are in mm. Window with Light Guide Design If a smaller window is desired while maintaining a wide effective viewing angle of the ISL29013, a cylindrical piece of transparent plastic is needed to trap the light and then focus and guide the light on to the device. Hence, the name light guide or also known as light pipe ...
