Hi Ryan, If the RLD amplifier is used in a configuration to drive an RLD electrode I understand the purpose of R11 and C27 but the idea in this thread is not to use an RLD electrode. So in this case I would expect the RLD amplifier to be configured as unity gain buffer, so RLDOUT and RLDINV shorted and no R11 and C27. The RLDREF_INT bit is set to 1 meaning that RLDOUT is at mid suply and used to bias the leads via the 10M resistors. Since the inputs are already pulled to the mid supply I see no use for R13 in this application. Kind regards,
↧
