TMP75AIDG4 datasheet by Texas Instruments

TMP75AIDG4 Frequently Asked Questions (FAQs)

• What is the accuracy of the TMP75AIDG4 over the entire operating temperature range?
  The TMP75AIDG4 has an accuracy of ±1°C over the range of -20°C to 100°C, and ±2°C over the range of -40°C to 125°C.
• How do I configure the TMP75AIDG4 for 12-bit or 13-bit resolution?
  The TMP75AIDG4 defaults to 12-bit resolution. To configure it for 13-bit resolution, set the RES bit in the configuration register (address 0x01) to 1.
• What is the conversion time for the TMP75AIDG4?
  The conversion time for the TMP75AIDG4 is 30 ms for 12-bit resolution and 60 ms for 13-bit resolution.
• Can I use the TMP75AIDG4 in a multi-drop configuration?
  Yes, the TMP75AIDG4 supports multi-drop configuration, allowing multiple devices to share the same bus. Each device must have a unique address set using the A0, A1, and A2 pins.
• How do I handle the alert output (ALERT) pin?
  The ALERT pin is an open-drain output that goes low when the temperature exceeds the threshold set in the T_HIGH or T_LOW registers. It can be connected to a microcontroller interrupt pin or used to trigger an external circuit.
