V or less. Check the preamplifier voltage input and power supply specifications and
headstage gain to determine the voltage range of the system.
The table below lists the input voltage ranges for the 16 channel ECoG headstages
for either a +/- 1.5 V or +/- 2.5 V power source.

Pinout
The numbers on the pinout diagram above show the channel connections to the
amplifier.
A three position switch is used to connect either REFa, REFb, or GND to the REF
line on the DB26 PreAmplifier/Digitizer connector.
The headstage does not provide access to ground and instead relies on the use of
the external ground on the preamplifier/digitizer.
