All voltages are referenced to ground. Currents into the IC are positive and out of the IC are negative.
Digital Inputs are at rail. FETG is disconnected SDA = SCL = 1.
See Safety Shutdown (FETG) Output Section for details.
Eight ranges allow the full-scale range to change from 625mV to 2.5V.
This specification applies to the expected full-scale value for the selected range. See Comp Ranging byte for available full-
scale ranges.
Eight ranges allow the full-scale range to change from 312.5mV to 1.25V.
The output impedance of the DS1863 is proportional to its scale setting. For instance, if using the 1/2 scale, the output
impedance would be 1.5kΩ.
This specification applies to the expected full-scale value for the selected range. See Mod Ranging byte for available full-
scale ranges.
See APC/Quick-Trip Sample Timing section for details.
