BOD
Burnout Detect. When enabled, this connects a positive current source to the positive channel and a negative
bit 6
current 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 is used, the internal voltage reference should be disabled.
bit 5
0 = Internal Voltage Reference Off for external reference.
1 = Internal Voltage Reference On (default). Note that in this mode, REFIN must be connected to AGND.
VREFH
Voltage Reference High Select. The internal voltage reference can be selected to be 2.5V or 1.25V.
bit 4
0 = REFOUT/REF IN+ is 1.25V.
1 = REFOUT/REF IN+ is 2.5V (default).
EBUF
Enable Buffer. Enables 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. Input signal limited to AVDD 1.5V.
PGA20
Programmable Gain Amplifier. Sets the gain for the PGA from 1 to 128.
