RESISTANCE 2-WIRE MEASUREMENT
AVDD = +6 V to +28.8 V, AVSS = −2.5 V to −18 V, AGND = DGND = 0 V, REFIN = +2.5 V (ideal), DVCC = +2.7 V to +5.5 V, AVCC = +4.5
V to +5.5 V, and all specifications are at TA = −40°C to +105°C, unless otherwise noted. RSENSE = 100 Ω (ideal), and CLOAD = 4.7 nF per the
recommended configuration.
