Photometric Sensor for Gesture and Proximity

Analog Devices Inc.

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 1.8V 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.
