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... Sutton
