The OPT3101 device is a high-speed, high-resolution AFE for continuous-wave,time-of-flight based proximity sensing and range finding. The device integrates the complete depthprocessing pipeline that includes the ADC, timing sequencer, and the digital processing engine. Thedevice also has a built-in illumination driver that covers most of the target applications.
Given the high ambient rejection ratio, the device can support very high ambientconditions, including full sunlight of 130 klx.
The timing sequencer is highly configurable to provide for application-specifictrade-offs of power versus performance.
The device provides depth data that consists of phase, amplitude, and ambientmeasurements. The calibration subsystem supports phase-data calibration for inaccuracies resultingfrom temperature and crosstalk.
