+      In addition to consuming the measurement services of a voltage
+      output channel, the voltage divider can act as a provider of
+      measurement services to other devices. This is particularly
+      useful in scenarios wherein an ADC has an analog frontend,
+      such as a voltage divider, and then consuming its raw value
+      isn't interesting. In this case, the voltage before the divider
+      is desired.
