A Low Power, High Sensitivity, Light-to

Digital Sensor With I

The ISL29020 is a low power, high sensitivity, integrated light

sensor with I

state-of-the-art photodiode array provides close-to human

eye response and good IR rejection. This ADC is capable of

rejecting 50Hz and 60Hz flicker caused by artificial light

sources. The lux range select feature allows the user to

program the lux range for optimized counts/lux.

In normal operation, typical power consumption 55µA. 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 I

power consumption can be reduced to less than 1µA when

powered down.

Designed to operate on supplies from 2.25V to 3.3V with I

supply from 1.7V to 3.6V, the ISL29020 is specified for

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

NOTE: These Intersil Pb-free plastic packaged products employ

special Pb-free material sets; molding compounds/die attach

materials and NiPdAu plate - e4 termination finish, which is RoHS

compliant and compatible with both SnPb and Pb-free soldering

operations. Intersil Pb-free products are MSL classified at Pb-free

peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
