Analog Devices Inc. ADR1001E-EBZ Evaluation Board allows the evaluation of the ADR1001, an ultrastable 6.6V shunt voltage reference with a resistor divider in a 20-terminal LCC package. Isolated power means the reference output is effectively floated, removing possible ground loops. The isolation is bridged only by a 1MΩ resistor. Power can be supplied via a USB-C™ cable or 5V can be applied to VUSB, or power can be back driven onto the regulator outputs at VPRE or V+. The ultra-stable 6.6V output is divided to a precision-trimmed 5V, routed to both banana jacks and an edge-mounted SMA connector.
