ADUX1020

Photometric Sensor for Gesture and Proximity


Manufactured by:

Product Details

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.

One inexpensive standard surface mount, broad angle or narrow angle IR LED (depending upon application) is required. This LED mounts externally to the ADUX1020.

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.

Applications

  • Gesture for user interface (UI )control in portable devices
  • Industrial/automation monitoring
  • Presence detection
  • Angle sensing

Product Details

The ADUX1020-EVAL-SDP evaluation kit provides users with a simple means of interfacing with the ADUX1020, collecting data from the ADUX1020, and evaluating gesture recognition capabilities.


The ADUX1020-EVAL-SDP is a kit that includes the ADUX1020-EVAL-SMALL and the ADUX1020-EVAL-MCM.


The evaluation kit requires the Optical Gesture Evaluation Tool, which can be downloaded from the ADUX1020-EVAL-SDP product page, a graphical user interface (GUI) that provides users with low level and high level configurability, real-time data analysis, and user datagram protocol (UDP) transfer capability so the evaluation board can easily interface to a PC.


The USB port of the PC powers the ADUX1020-EVAL-SDP kit. On-board voltage regulators provide voltage supplies for the ADUX1020.


The evaluation board schematics indicate signal names for easy identification. For additional information on the functionality of the ADUX1020, refer to the ADUX1020 data sheet.
