BOD

Burnout Detect. When enabled this connects a positive current source to the positive channel and a negative current

bit 6

source to the negative channel. If the channel is open circuit then the ADC results will be full-scale (buffer must be enabled).

0 = Burnout Current Sources Off (default).

1 = Burnout Current Sources On.

EVREF

Enable Internal Voltage Reference. If an external voltage reference is used, the internal voltage reference should

bit 5

be disabled.

0 = Internal Voltage Reference Off.

1 = Internal Voltage Reference On (default).

VREFH

Voltage Reference High Select. The internal voltage reference can be selected to be 2.5V or 1.25V.

bit 4

0 = REFOUT/REFIN+ is 1.25V.

1 = REFOUT/REFIN+ is 2.5V (default).

EBUF

Enable Buffer. Enable the input buffer to provide higher input impedance but limits the input voltage range and

bit 3

dissipates more power.

0 = Buffer disabled (default).

1 = Buffer enabled.

PGA2-0

Programmable Gain Amplifier. Sets the gain for the PGA from 1 to 128.
