DESIGN NOTES

Several features are included to make this sensor board a complete solution. 

ESD diodes on Send/Receive lines 

MOSFET buffers on input  

  • Send is Active-High 

DC-coupled output for ambient light disturbance rejection 

Buffered Output 

  • Op-amp follower for analog output on Receive line 

The current-related resistors were chosen following the Vishay application note for a long distance / low reflectivity scenario. Thus, for optimal performance the board should be supplied at 5V, although the Send input is buffered by a small MOSFET with a Vgs of 1.8V.
