Description
AI
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 depth processing pipeline that includes the ADC, timing sequencer, and the digital processing engine. The device 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 ambient conditions, including full sunlight of 130 klx.
The timing sequencer is highly configurable to provide for application-specific trade-offs of power versus performance.
The device provides depth data that consists of phase, amplitude, and ambient measurements. The calibration subsystem supports phase-data calibration for inaccuracies resulting from temperature and crosstalk.
