Note 1: All voltages are referenced to ground. Current into the IC is positive, and current out of the IC is negative.
Note 2: Inputs are at supply rail. Outputs are not loaded.
Note 3: This parameter is guaranteed by design.
Note 4: Full-scale is user programmable.
Note 5: A temperature conversion is completed and the DAC values are recalled from the LUTs and V
Note 6: This specification is the time it takes from RSSI1_ and RSSI2_ voltage falling below the LLOS_ trip threshold to LOSOUT
Note 7: This specification is the time it takes from RSSI1_ and RSSI2_ voltage rising above the HLOS_ trip threshold to LOSOUT
Note 8: I
Note 9: C
Note 10: EEPROM write begins after a STOP condition occurs.
