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.
