Instructions for DS1643-120

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
   • Connect the ground (GND) pin to the system ground.

2. Temperature Measurement:

   • The device measures temperature with a resolution of 12 bits.
   • The typical accuracy at 25掳C is 卤0.5掳C.
   • The conversion time for a temperature measurement is 750 ms.

3. Standby Mode:

   • To minimize power consumption, use the standby mode where the current draw is between 1 渭A and 5 渭A.

4. Communication:

   • The DS1643-120 uses the I2C communication protocol.
   • Ensure the I2C bus lines (SDA and SCL) are properly pulled up to VCC using appropriate resistors.
   • Set the address pins (ADDR) as required to configure the device address on the I2C bus.

5. Operating and Storage Temperature:

   • The operating temperature range is from -40掳C to 85掳C.
   • The storage temperature range is from -65掳C to 150掳C.

6. Output Current:

   • The maximum output current (Iout) is 100 渭A. Ensure that the load does not exceed this limit.

7. Address Pin Input Current:

   • The input current for the address pins (IADDR) is typically between 1 渭A and 5 渭A.

8. Handling and Storage:

   • Handle the device with care to avoid damage.
   • Store the device in a dry environment within the specified storage temperature range.
