SBAS566A – DECEMBER 2011 – REVISED SEPTEMBER 2012
The reference voltage for the right leg drive can be chosen to be internally generated (AVDD + AVSS)/2 or it can
be provided externally with a resistive divider. The selection of an internal versus external reference voltage for
the RLD loop is defined by writing the appropriate value to the RLDREF_INT bit in the MISC2 register.
If the RLD function is not used, the amplifier can be powered down using the PDB_RLD bit. This bit is also used
in daisy-chain mode to power-down all but one of the RLD amplifiers.
The functionality of the RLDIN pin is explained in the Input Multiplexer section. An example procedure to use the
RLD amplifier is shown in the Right Leg Drive subsection of the Quick-Start Guide section.
RLD Configuration with Multiple Devices
