EVAL-ADT7422MBZ

Product Details

The EVAL-TempSense-ARDZ is an evaluation board kit containing three evaluation boards that allows easy evaluation of the functionality of ADIs precision digital temperature sensors. Interface to the sensors can be either directly on the Arduino shield or by ribbon cable connected to external sensors. Consult the ADT7410, ADT7420, ADT7422, ADT7310, and ADT7320 data sheets in conjunction with the user guide when using the EVAL-TempSense-ARDZ with the Arduino integrated development environment (IDE) or the Analysis Control Evaluation (ACE) Software.

The ADT7410, ADT7420, ADT7422, ADT7310, and ADT7320 are high accuracy digital temperature sensors offering breakthrough performance over a wide industrial temperature range. The devices contain an internal band gap reference, a temperature sensor, and a 16-bit analog-to-digital converter (ADC) to monitor and digitize the temperature to 0.0078°C resolution. The devices are available in I²C or SPI versions.

Product Details

The ADMX2001 is a measurement module that simplifies the development of impedance measurement systems or can be used to enhance the capabilities of existing test platforms. Using high-performance mixed-signal and processing algorithms, the ADMX2001 can measure changes in capacitance as small as 0.1fF and resistance values up to 20MΩ, often required to test semiconductor devices, electronic components, and sensors. Moreover, built-in measurement algorithms enable the ADMX2001 to deliver fully calibrated complex impedance or admittance measurement results in various formats, including parallel and series combinations of resistance, capacitance, and inductance.
