The ISL29035 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 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.

For ambient light sensing, an internal 16-bit ADC has been

designed based upon the charge-balancing technique. The

ADC conversion time is nominally 105ms and is user

adjustable from 11µs to 105ms, depending on oscillator

frequency and ADC resolution. In normal operation, typical

current consumption is 57µA. In order to further minimize

power consumption, two power-down modes have been

provided. If polling is chosen over continuous measurement of

light, the auto-power-down function shuts down the whole chip

after each ADC conversion for the measurement. The other

power-down mode is controlled by software via the I2C

interface. The power consumption can be reduced to less than

0.3µA when powered down.

The ISL29035 supports a software brownout condition

detection. The device powers up with the brownout bit asserted

until the host clears it through the I2C interface.

The ISL29035 supports a software and hardware interrupt that

remains asserted until the host clears it through the I2C

interface. 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 ISL29035 is specified for

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