Time of Flight (ToF) Signal Processing IC
Jump to Page Section:
Overview
Description
The ISL29501 is a Time of Flight (ToF) based signal processing integrated circuit. The sensor enables low cost, low power, and long range optical distance sensing when combined with an external emitter and detector. The ISL29501 has a built-in current DAC circuit that drives an external LED or laser. The modulated light from the emitter is reflected off the target and is received by the photodiode. The photodiode then converts the returned signal into current, which is used by the ISL29501 for signal processing. An on-chip Digital Signal Processor (DSP) calculates the time of flight, which is proportional to the target distance. The ISL29501 is equipped with an I2C interface for configuration and control. Use of an external photodiode and emitter allows the user to optimize the system design for performance, power consumption, and distance measurement range that suit their industrial design. The ISL29501 is wavelength agnostic and permits the use of other optical wavelengths if better suited for applications.
