4.1. Voltage Monitoring System

The Agilex™ 5 voltage monitoring system uses a built-in 7-bit analog to digital converter (ADC). The ADC can sample up to one kilo samples per second (KSPS).
Figure 4.  Agilex™ 5 Voltage Sensor


The voltage sensor has the following capabilities:

  • Monitor external voltages up to 1.10 V through two pairs of differential input pins.
  • Monitor internal power supplies. For internal high-voltage rails in channels 3, 4, 5, and 9, a voltage divider function divides the input voltage by half and feeds the voltage to the ADC. The SDM then doubles the ADC reading to get the actual voltage.
