3 PA Monitoring

The AMC7908 has a 16-bit ADC used for voltage, current, and temperature monitoring. Each ADC input has user configurable high and low alarm limits. If the ADC value exceeds these limits, an internal alarm triggers and the device clamps the DAC and OUT outputs to VSS. The user can select which specific DAC and OUT outputs get clamped for each specific alarm. In addition, the ADC also monitors the VCC, VSS, and internal reference and trigger an alarm condition if these voltages are out of range. Figure 3-1 shows the ADC alarm block diagram.
