Planning to build a quadruple indicator for automotive (lambda) oxygen sensors outputted voltage with four LM3914 in dot mode in 0.1 to 0.9 V scale.
Wondering what is the typical load these sensors work happily with ?
I believe the LM3914 is over 20K input resistance, but cannot tell for sure. Do you know that too ?
