ADS1299: ADS1299 Signal noise ratio
Part Number: ADS1299
Hello, please help me confirm whether to add instrument amplifier and operational amplifier before feeding the collected electrode eeg signal into the AD1299 chip?
Or can I do a simple RC filter and then directly connect to AD1299?
Q2:Is the BIAS schematic partially correct, with BIAS directly connected to the BIAS electrode?
In reply to user5947491:
I'll send you a note to forward the schematic over.
