INPUT MULTIPLEXER (MEASURING THE RIGHT LEG DRIVE SIGNAL)

Also, the RLDOUT signal can be routed to a channel (that is not used for the calculation of RLD) for

measurement. Figure 52 shows the register settings to route the RLDIN signal to channel 8. The measurement is

done with respect to the voltage on the RLDREF pin. If RLDREF is chosen to be internal, it would be at (AVDD +

AVSS)/2. This feature is useful for debugging purposes during product development.

(1) Typical values for example only.
