Voltage Monitor
The Fusion Analog Quad offers a robust set of voltage-
monitoring capabilities unique in the FPGA industry. The
Analog Quad comprises three analog input pads—
Analog Voltage (AV), Analog Current (AC), and Analog
Temperature (AT)—and a single gate driver output pad,

signal. Care must be taken in this mode not to drive the
ADC into saturation by applying an input voltage greater
than the reference voltage. The internal reference
voltage of the ADC is 2.56 V. Optionally, an external
reference can be supplied by the user. The external
reference can be a maximum of 3.3 V DC.
