POWER MONITORING SPECIFIC APPLICATIONS

All channels of the ADS131E0x family of devices are exactly identical, yet independently configurable, thus

giving the user the flexibility of selecting any channel for voltage or current monitoring. An overview of this

system is illustrated in Figure 43. Also, the simultaneously sampling capability of the device allows the user to

monitor both the current and the voltage at the same time. The full-scale differential input voltage of each

channel is determined by the PGA gain setting (see the CHnSET: Individual Channel Settings section) for the

respective channel and VREF (see the CONFIG3: Configuration Register 3 section). Table 12 summarizes the full-

scale differential input voltage range for an internal VREF.
