General Description:

The TH09C integrates one relative humidity sensor and one high-accuracy temperature sensor. The device is encapsulated in a QFN4 package and includes an I²C slave interface for communication with a master processor. 

Key Benefits and Features:

• Ultra-accurate: * Temperature sensor (±0.15°C) 

                          * Relative humidity sensor (Typ:±2.0%RH)

• Wide sensing range: * Temperature operating range (–40°C to 100°C) 

                                   * Relative humidity operating range (0% to 100%)

• Wide operating voltage: 1.71V to 3.60V

• Small foot-print: 2.0mm x 2.0mm x 0.75mm

• Industry standard two-wire interface: Standard (100kbit/s) and fast (400kbit/s) I²C

• Low power: * Automatic low-power standby when not measuring 

                      * Active current: 6.6μA @ 1Hz (1.8V)

                      * Standby current: 40nA

• Cost effective: * Digital pre-calibrated relative humidityand temperature sensor 

                          *  Output directly in %RH and Kelvin 

                          *   Wide supply voltage range

• High reliability: Long-term stability
