Appendix A: Glossary

Common Mode Voltage (VCM ) : The voltage about which a differential voltage swings. When this is measured on the SDAIBB it is calculated with all voltage readings taken in reference to GND of the SDAIBB as

(IN + + IN − ) 2 . Note that when one of the inputs is connected to GND of

the SDAIBB the common mode voltage changes as the differential voltage changes.

Differential Voltage (VDIFF ) : The difference in voltage across two points

such as the two leads on a thermocouple. When this is measured on the SDAIBB it is calculated with all voltage readings taken in reference to

GND of the SDAIBB as IN + − IN − .

Gain (G) : The amount by which the input is multiplied before it is output.

Gain =

Vout

IN +

− IN −

 

Impedance Mismatch: When the output impedance of sensor is different enough from the input impedance of the data acquisition device to cause improper sensor readings.

Negative Input Differential: When the voltage and IN- is higher than the voltage at IN-. IN + − IN − ≤ 0

Negative Rail: The lowest possible voltage that can be output. For the SDAIBB there is a negative rail internal to the buffer and a negative rail on the output of the buffer.

Positive Rail: The highest possible voltage that can be output. For the SDAIBB there is a positive rail internal to the buffer and a positive rail on the output of the buffer.
