Compiler/ADS1298R: ADS1298R

Part Number: ADS1298R


Tool/software: TI C/C++ Compiler

Hi TI:

When I designed the circuit diagram with ADS1298R, I could not use the Wilson center terminal (WCT) and goldberg center terminal (GCT) required for the right leg drive (RLD) and standard 12 lead ECG.

At present, the pin is analog input, including TESTN_FACE_OUT2, TESTP_FACE_OUT1, WCT, RLDINV, RLDREF and RLDIN.

May I ask how to handle these unused pins when they are designed? Should they be suspended (will the suspension cause the charge accumulation to generate high pressure on the pins) or grounded?

Thanks!

Best,

Kevin
