Instructions for Using the LM75ADP:
Power Supply:
- Ensure the supply voltage (Vcc) is within the range of 2.8V to 5.5V.
- Connect Vcc to the positive power supply and GND to the ground.
Temperature Measurement:
- The LM75ADP continuously monitors the temperature and provides a digital output.
- The temperature sensor range is from -55°C to 125°C with a typical accuracy of ±1°C at 25°C and ±2°C over the full range.
Output Configuration:
- The output is open-drain, requiring a pull-up resistor to Vcc.
- The pull-up resistor value should be chosen based on the desired output current and bus capacitance.
Overtemperature Shutdown:
- The overtemperature shutdown threshold (TOS) and hysteresis (THYST) can be programmed via the SMBus/I2C interface.
- Set the TOS and THYST values according to your application requirements.
Communication:
- Use the SMBus/I2C protocol to read temperature data and configure the device.
- The default I2C address is 0x48, but it can be changed by connecting the A0, A1, and A2 pins to Vcc or GND.
Conversion Time:
- The conversion time is approximately 300 ms. Ensure that the system waits this duration before reading the temperature data.
Storage and Operating Temperature:
- Store the device between -65°C and 150°C.
- Operate the device within the temperature range of -40°C to 125°C.
Handling:
- Handle the device with care to avoid static discharge and physical damage.
- Follow proper ESD (Electrostatic Discharge) precautions when handling the device.
By following these instructions, you can effectively use the LM75ADP for temperature monitoring in your applications.
