ADC leakage current followup - TomW

2006-03-07 by Sutton Mehaffey

Tom,

Since Philips isn't responding / hasn't responded to my ADC leakage
question, as you said would probably happen, is it safe to say the
leakage at the AD0 channels is probably 4ua max?  If so, I may put in
extra circuitry to handle to slop in measuring battery voltage, or I
may just add another ADC to my board.  I had an ADC on an 8051 project
and it worked great.  I just thought that an onboard ADC would
eliminate extra parts.  Maybe not...
