Fully Integrated Proximity and
Ambient Light Sensors
The VCNL4010, VCNL4020, and VCNL4020X01 are fully integrated proximity and ambient light sensors.
Fully integrated means they contain the infrared emitter and photo detector for proximity, an ambient light
sensor, a signal processing IC, and I2C communication interface. The VCNL3020 supports only proximity
sensing; it does not contain an ambient light sensor. With full 16-bit resolution for both the proximity and
ambient features, user-defined interrupt levels, and multiple packaging options, the VCNL portfolio will
fulfill your requirements.
FEATURES
• Proximity function
–– 16-bit resolution
–– Excellent crosstalk immunity
–– Programmable LED drive current from
10 mA to 200 mA in 10 mA steps
–– Programmable measurement rate from
1 Hz to 250 Hz
–– Proximity distance up to 20 cm (8 in.)
–– Includes driver for an external emitter
for increased range
• Ambient light function
–– Built-in ambient light PIN photodiode
with close to human eye sensitivity
characteristic
–– 16-bit dynamic range for ambient light
detection from 0.25 lx to 16 klx
–– 100 Hz and 120 Hz flicker noise rejection

CURRENT CONSUMPTION
When only the I2C interface is active, the current consumption is only 1.5 μA. When proximity is active, the current
consumption is a function of the emitter current and the measurements per second. A current calculator is available at
http://www.vishay.com/optoelectronics/opto-sensors-calculator/.
EVALUATION KITS
An evaluation kit is available for each of the sensors. Contact any catalog distributor or a local Vishay sales representative
to purchase the Sensor Starter Kit and contact [email protected] for kits with the VCNL4010,
VCNL4020X01, or VCNL3020.
