General Specifications (Continued) 1.9 < VDD < 3.6 V; TA = –40 to 85 °C (G grade) or –40 to 125 °C (I/Y grade); default conversion time unless otherwise noted. Parameter Symbol Test Condition Min Typ Max Unit Notes: 1. Initiating a RH measurement will also automatically initiate a temperature measurement. The total conversion time will be tCONV(RH) + tCONV(T). 2. No conversion or I2C transaction in progress. Typical values measured at 25 °C. 3. Occurs once during powerup. Duration is <5 msec. 4. Occurs during I2C commands for Reset, Read/Write User Registers, Read EID, and Read Firmware Version. Duration is <100 µs when I2C clock speed is >100 kHz (>200 kHz for 2-byte commands). 5. Additional current consumption when HTRE bit enabled. See Section “5.5. Heater” for more information. |
