Notes:

R 1. Initiating a RH measurement will also automatically initiate a temperature measurement. The total conversion time will

tbe tCONV(RH) + tCONV(T).

2. No conversion or I2C transaction in progress. Typical values measured at 25 °C.

o3. Occurs once during powerup. Duration is <5 msec.

4. Occurs during I2C commands for Reset, Read/Write User Registers, Read EID, Read Firmware Version, Read/Write

N Thermistor Coefficients and Measure Analog Voltage or Thermistor Temperature. Duration is <50 μs for all commands

except Measure Analog Voltage or Thermistor Temperature, which has <150 μs duration when Thermistor Correction is

enabled.

5. Additional current consumption when HTRE bit enabled. See Section “5.6. Heater” for more information.
