Samir,
Before using any IC it is highly recommended that you read the datasheet and any user guides available for the part as these documents accurately describe how the part functions, how it interfaces with other components (such as microcontrollers) and what level of performance the IC is capable of. All of your above questions are answered in the TMP006 datasheet: http://www.ti.com/lit/gpn/tmp006 and user guide: http://www.ti.com/litv/pdf/sbou107
