Test Conditions/Comments
REFIN = REFIN(+) − REFIN(−)
When VREF = AVDD, the differential input must be
limited to (0.9 x VREF/gain) if the in-amp is active.
NOXREF bit active if VREF < 0.3 V
AVDD = 5 V
AVDD = 3 V
Continuous current
AVDD = 3 V, ISOURCE = 100 µA
AVDD = 3 V, ISINK = 100 µA
AVDD = 5 V, ISOURCE = 200 µA
AVDD = 5 V, ISINK = 800 µA
DVDD = 5 V
DVDD = 3 V
DVDD = 3 V or 5 V
DVDD = 5 V
DVDD = 5 V
DVDD = 5 V
DVDD = 3 V
DVDD = 3 V
DVDD = 3 V
VIN = DVDD or GND
All digital inputs
DVDD = 3 V, ISOURCE = 100 µA
DVDD = 3 V, ISINK = 100 µA
DVDD = 5 V, ISOURCE = 200 µA
DVDD = 5 V, ISINK = 1.6 mA
