The ISL29010 is an integrated light sensor with I2C

interface. It has an internal signed15-bit integrating type

ADC designed based on the charge-balancing conversion

technique. 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, power consumption is typically 250µA.

Furthermore, a power-down mode can be controlled by

software via the I2C interface, reducing power consumption

to less than 1µA.

Designed to operate on supplies from 2.5V to 3.3V, the

ISL29010 is specified for operation over the -40°C to +85°C

ambient temperature range.

NOTES:

1. Please refer to TB347 for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special

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

and 100% matte tin plate - e3 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.

3. For Moisture Sensitivity Level (MSL), please see device

information page for ISL29010. For more information on MSL

please see tech brief TB477.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and

result in failures not covered by warranty.

NOTE:

4. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See

Tech Brief TB379.

IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests

are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

Electrical Specifications VDD = 3V, TA = +25°C, REXT = 100k, unless otherwise specified, Internal Timing Mode operation (See

NOTES:

5. Fluorescent light is substituted by a green LED during production.

6. The voltage threshold levels of the SDA and SCL pins are VDD dependent: VTL = 0.35*VDD. VTH = 0.65*VDD.

7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
