Pin Function Specifications:
Below is a detailed breakdown of the TMP117AIDRVR’s pin functions:
Pin Number Pin Name Pin Function Description 1 VDD Power Supply Input. Connect to a stable voltage source (typically 2.7V to 5.5V). This pin powers the TMP117. 2 SDA I2C Data Line. Used for bidirectional data transfer in I2C Communication . Connect to the data line of your I2C bus. 3 SCL I2C Clock Line. Provides the clock signal for I2C communication. Connect to the clock line of your I2C bus. 4 ADDR I2C Address Pin. This pin is used to set the lower bit of the I2C address. It can be pulled high or low to select one of the two possible I2C addresses. 5 GND Ground. Connect to the system ground to complete the circuit. 6 DRDY Data Ready Pin. This pin is active low and indicates that a new temperature reading is available. When low, data from the TMP117 can be read via I2C. 7 NC No Connection. This pin is not connected internally and can be left floating or grounded. 8 NC No Connection. Same as Pin 7, this pin has no internal connection and can be left unused.Circuit Principle Instructions:
Power Supply (VDD): The TMP117 operates on a voltage range from 2.7V to 5.5V, and the power supply must be stable and within this range to ensure proper functioning of the sensor. I2C Communication: The TMP117 uses I2C for communication. SDA (Serial Data) and SCL (Serial Clock) must be connected to the respective lines of the I2C bus. The ADDR pin allows you to configure the sensor's I2C address, which is essential for proper communication with multiple devices on the same bus. Data Ready Pin (DRDY): This pin signals when new data is available. The sensor’s data can only be read when DRDY is low, indicating that the measurement is complete and the data is ready for transmission over I2C.20 FAQ (Frequently Asked Questions) for TMP117AIDRVR:
