Evaluation and Demonstration Boards and Kits

Evaluation and demonstration boards and kits are products designed to allow engineers to assess and evaluate a specific functional operation and also for design and proof-of-concept tasks. An example of such a board is the AFE5807EVM, which is based on Texas Instruments’ AFE5807 analog front end (AFE) for time-of-flight sensor systems.

AFE5807EVM

The AFE5807EVM is an evaluation module that supports and facilitates the evaluation of the AFE5807. It includes on-board operational amplifiers and passive components to provide a robust test bed, enabling engineers to quickly get up and running with the AFE5807. The AFE5807EVM was designed to operate with single supply voltage from 2.8V to 5.5V and its power consumption is typically lower than 95mW. It also includes 16 configurable GPIOs for providing flexibility to the user.

Application Field

The AFE5807EVM is typically used in time-of-flight (ToF) sensors for proximity sensing, obstacle avoidance, drone navigation, and gesture recognition. These applications often require efficient, accurate, and reliable ToF sensors. The AFE5807 is based on the pulse-to-amplitude conversion (PAC) architecture which enables accurate distance measurements and fast response times.

Working Principle

The AFE5807EVM works in conjunction with the AFE5807 chip as a complete ToF sensing system. It measures distances up to 1.24 m using light pulses and light-to-digital conversion (LDC) measurements. When the system is powered on, the AFE5807EVM sends a programmed waveform to the AFE5807, which in turn sends an output signal to the emitter. Then the emitter will emit an optical pulse traveling through the medium, and reflected back to the receiver. The returning signal is then converted by the receiver and reads as an analog input signal to the AFE5807. The AFE5807 then amplifies and converts the signal into a digital value and transmits it back to the AFE5807EVM. The AFE5807EVM then calculates the distance from this signal input and the programmed waveform.

Conclusion

The AFE5807EVM provides engineers with a reliable and accurate test bed for evaluating the AFE5807. It is a low power consuming evaluation module that supports a wide range of applications including proximity sensing, gesture recognition, drone navigation, and obstacle avoidance. It works in conjunction with the AFE5807 chip to accurately and efficiently measure distances.
