Photometric Sensor  
for Gesture and Proximity  
ADUX1020  
Data Sheet  
FEATURES  
GENERAL DESCRIPTION  
Multifunction photometric sensor and signal conditioning  
Fully integrated AFE, ADC, LED driver, and timing core  
Usable for multiple optical measurement applications,  
including gesture control and proximity sensing  
Enables an ambient light rejection capability using both  
optical and analog filtering  
On-chip programmable flexible current sink for external LED  
High sensitivity and signal-to-noise ratio (SNR)  
High resolution position measurement  
Gesture recognition with 0.5 cm to 15 cm range  
Proximity sensing to 20 cm  
400 kHz I2C interface  
Gesture/proximity works under infrared (IR) transparent  
glass or other materials  
Simple integration with optics; no need for precise  
alignment and no lens is required  
Low power operation  
The ADUX1020 is a highly efficient photometric sensor with an  
integrated 14-bit analog-to-digital converter (ADC) and a 20-bit  
burst accumulator that works in concert with a flexible light  
emitting diode (LED) driver. It is designed to modulate a LED  
and measure the corresponding optical return signal. The digital  
engine includes circuitry and control for data aggregation and  
proximity detection.  
The data output and device configuration use a 1.8 V I2C interface.  
The control circuitry includes flexible LED pulse width and  
period generation combined with synchronous detection. This  
circuitry is complemented by a low noise, low power, and wide  
dynamic range configurable analog front end (AFE), clock  
generation, LED driver, and digital logic for position and smart  
sample mode (event driven x, y coordinates, relative z data).  
This complete AFE features ambient light rejection, avoiding  
corruption due to external interference.  
1.8 V analog/digital core  
One inexpensive standard surface mount, broad angle or narrow  
angle IR LED (depending upon application) is required. This  
LED mounts externally to the ADUX1020.  
8-lead, 2 mm × 3 mm, 0.65 mm height LFCSP  
APPLICATIONS  
Gesture for user interface (UI) control in portable devices  
Industrial/automation monitoring  
Presence detection  
Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP,  
the ADUX1020 is specified over an operating temperature  
range of −40°C to +85°C.
