Test Conditions/Comments
Minimum supply required on one of VH, VPx pins
Maximum VDDCAP = 5.1 V, typical
VDDCAP = 4.75 V
Regulated LDO output
Minimum recommended decoupling capacitance
VDDCAP = 4.75 V, PDO1 to PDO10 off, ADC off
VDDCAP = 4.75 V, PDO1 to PDO6 loaded with 1 μA
each, PDO7 to PDO10 off
Maximum additional load that can be drawn from all
PDO pull-ups to VDDCAP
Running round-robin loop
1 ms duration only, VDDCAP = 3 V
Midrange and high range
Low range and midrange
No input attenuation error
No input attenuation error
VREF error + DAC nonlinearity + comparator offset error
+ input attenuation error
Minimum programmable filter length
Maximum programmable filter length
The ADC can convert signals presented to the VH,
VPx, and VXx pins; VPx and VH input signals are
attenuated depending on the selected range; a signal
at the pin corresponding to the selected range is
from 0.573 V to 1.375 V at the ADC input.
