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.
