Analyze Internal Voltage and Temperature Sensors

The XADC also has several internal sensors that it digitizes. These include a temperature
sensor and FPGA voltage supply sensors. Select the Sensor Data tab to view the data
corresponding to the four sensors, as shown in

Power Monitoring with XADC on AC701

The AC701 evaluation board and AMS Evaluator tool offer a complete system monitoring
solution. The AC701 uses the XADC to measure voltage and load current on nine of the
onboard power supplies. Voltage is measured using remote sensing. Current is measured
across a sense resistor with individual current sense op amps. Power is then calculated for
each of the nine rails by multiplying voltage x current. An external multiplexer is also used
