 The ADR1399H-EBZ allows the evaluation of the ADR1399KHZ, ultra-stable 7.05V Shunt Voltage Reference in 4-lead TO-46 package. ​ The ADR1399H-EBZ allows the evaluation of the ADR1399KHZ, ultra-stable 7.05V Shunt Voltage Reference in 4-lead TO-46 package. ​
-The 4-layer board has had ground ​layers cut away under the DUT, ensuring high thermal insulation of the heated DUT.  In the DUT area, only the bottom layer has a ground plane, and it is mesh rather than solid.+ 
 +The DUT is elevated on its leads in order to increase the thermal isolation from the 4-layer board ground ​planes. 
 Isolated power means that the Reference output is effectively floated, removing the likelihood of ground loops. ​ The isolation is bridged only by a 1Meg resistor. ​  Power may be supplied via the USB-C cable, or 5V may be applied to “VUSB”, or power may be back driven onto the regulator outputs at “VPRE” or V+”. Isolated power means that the Reference output is effectively floated, removing the likelihood of ground loops. ​ The isolation is bridged only by a 1Meg resistor. ​  Power may be supplied via the USB-C cable, or 5V may be applied to “VUSB”, or power may be back driven onto the regulator outputs at “VPRE” or V+”.
 The ultra-stable 7.05V is brought out to both banana jacks and to an edge mounted SMA connector. The ultra-stable 7.05V is brought out to both banana jacks and to an edge mounted SMA connector.
