The HART enabled Smart Transmitter Demo circuit, DEMO-AD5700D2Z, developed by ADI, has been compliance tested, verified and registered as an approved HART solution by the HART Communication Foundation. The registration certificate is available from the HCF website. This registration confirms that the AD5700 complies with the HART physical layer protocol and hence is a proven and verified solution.
The demo board allows the user to easily evaluate the combination of the 3 main building blocks:
- AD5700 Complete HART FSK Modem
- AD5421 16-bit 4-20mA loop-powered DAC
- ADuCM360 precision analog microcontroller with dual 24-bit sigma-delta ADCs
The complete solution has been written up as a Circuit From The Lab and is available for download from the analog.com website - search for CN-0267. The demo board itself is also available to order from the same webpage.
