Note 1:
All voltages are referenced to ground. Current into IC is positive, out of the IC is negative.
Note 2:
Digital inputs are at rail. FETG is disconnected. SDA = SCL = VCC. DAC1 and M4DAC are not loaded.
Note 3:
See the
Safety Shutdown (FETG) Output section for details.
Note 4:
Eight ranges allow the full-scale range to change from 625mV to 2.5V.
Note 5:
This specification applies to the expected full-scale value for the selected range. See the Comp Ranging byte for available
full-scale ranges.
Note 6:
Eight ranges allow the BMD full-scale range to change from 312.5mV to 1.25V.
Note 7:
The output impedance of the DS1865 is proportional to its scale setting. For instance, if using the 1/2 scale, the output
impedance would be approximately 1.56k
Ω.
Note 8:
This specification applies to the expected full-scale value for the selected range. See the Mod Ranging byte for available
full-scale ranges.
Note 9:
See the
APC and Quick-Trip Shared Comparator Timing section for details.
Note 10: Assuming an appropriate initial step is programmed that would cause the power to exceed the APC set point within four
steps, the bias current will be 1% within the time specified by the binary search time. See the
Bias and MOD Output During
Power-Up section.
Note 11: I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with the I2C stan-
dard mode.
Note 12: CB
total capacitance of one bus line in picofarads.
Note 13: EEPROM write begins after a STOP condition occurs.
Note 14: Guaranteed by design.
