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, Analog Gate (AG). There are
many common characteristics among the analog input pads. Each analog input can be configured to
connect directly to the input MUX of the ADC. When configured in this manner
no prescaling of the input 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.
