Test Conditions/Comments
Minimum supply required on one of VPx, VH
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, DACs 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
Six DACs on with 100 μA maximum load on each
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
