DS1721U+ Frequently Asked Questions (FAQ)

  • The DS1721U+ requires careful layout and routing to ensure accurate temperature measurements. It is recommended to keep the device away from high-current carrying traces, and to use a solid ground plane to minimize noise. Additionally, the thermistor inputs should be routed as differential pairs to minimize noise pickup.

  • The DS1721U+ does not require calibration for temperature measurements. However, it is recommended to perform a one-time calibration of the thermistor using a known temperature reference point to ensure accurate measurements.

  • The maximum cable length for the thermistor inputs depends on the specific application and noise environment. As a general guideline, cable lengths up to 10 feet (3 meters) are acceptable, but longer cables may be used with proper shielding and noise filtering.

  • No, the DS1721U+ is designed specifically for use with thermistors and is not compatible with thermocouples. Using a thermocouple with the DS1721U+ will result in inaccurate temperature measurements.

  • The DS1721U+ has a power-on reset (POR) circuit that initializes the device to a known state upon power-up. The POR circuit ensures that the device is in a reset state until the power supply has reached a minimum of 2.5V.
