ISL29033IROZ-EVALZ開發(fā)板套件編程器的評估板-傳感器規(guī)格書PDF中文資料

The ISL29033 is an integrated ambient and infrared light to

digital converter with I2C (SMBus Compatible) interface. Its

advanced, self-calibrated photodiode array emulates human

eye response with excellent IR rejection. The on-chip 16-bit

ADC is capable of rejecting 50Hz and 60Hz flicker caused by

artificial light sources. The lux range select feature allows

users to program the lux range for optimized counts/lux.

Power consumption can be reduced to less than 0.3μA when

powered down.

The ISL29033 supports a software and hardware interrupt that

remains asserted until the host clears it through the I2C

interface. The function of ADC conversion continues without

stopping after interrupt is asserted.

Designed to operate on supplies from 2.25V to 3.63V with an

I2C supply from 1.7V to 3.63V, the ISL29033 is specified for

operation over the -40°C to +85°C ambient temperature

range.
