EVAL-ADT7604-AZ

Product Details

The EVAL-ADT7604-AZ features the ADT7604 20-channel, data center thermal measurement and leak sensing system with EEPROM. The ADT7604 measures a wide variety of temperature sensors and digitally outputs the result in °C, °F, or Ω with 0.1°C accuracy and 0.001°C resolution. All signals are buffered and simultaneously digitized with two high-accuracy, 24-bit Δ-Σ ADCs.

The ADT7604 features accurate temperature measurement with copper trace sensors, which are thin copper traces integrated into PCBs or laminate substrates, and can be placed in mechanically hard-to-reach places to sense thermal hotspots. The ADT7604 also accurately measures resistive leak detectors for safety monitoring in liquid-handling systems.

The EVAL-ADT7604-AZ is a thermal measurement evaluation board with two copper trace sensors, two leak detectors, a 1kΩ thermistor and a PT-100 RTD. When connected to a DC2026C Linduino demo circuit and a host PC, the EVAL-ADT7604-AZ reports temperature, resistance, and fault status from multiple types of sensors through the graphical user interface (GUI).

The copper trace sensors require a one-time calibration prior to operation. The leak detection sensors can be configured to report either raw resistance between the metal traces or the percentage of sensor coverage. See the Calibration sections for detailed setup procedures.

The GUI supports the evaluation of all onboard sensors as well as external custom sensors: a custom copper trace sensor connected to J1 and a custom leak detection sensor connected to J3.

The ADT7604 is available in a 48-lead plastic LQFP package. The ADT7604 data sheet gives a complete description of this part, its operation, and applications information. The ADT7604 data sheet must be read in conjunction with this user guide to properly use the evaluation circuit EVAL-ADT7604-AZ.
