Part Number: ADS1299 I drew a schematic diagram for a 2-channel ADS1299-4 with external reference and bias electrodes, and was wondering if I could have it proof-read. Additional analog filtering components are to be added to leads. Unipolar supply configuration was used - analog supply is 5V and digital supply is 3V. Unused channels were pulled high Since we are using a separate reference electrode, we just used the positive electrode terminals Bias electrode was also defined as such. GPIOs assigned and CLKSEL pulled high to use internal oscillator GPIO1-4 and voltage capacitors defined as such. Leftover pins grounded and un-used pins left floating. 1) Would there be a benefit to changing to a bi-polar supply configuration? 2) Is it correct to leave BIASIN floating and BIASREF grounded?
