<p>The application is directed to a resistance bridge measurement circuit (100) configured to perform an internal self-check. The resistance bridge measurement circuit may include two or more internal resistors (104,106). In one embodiment, the resistance bridge measurement circuit may be configured to measure a first voltage across one of the resistors and a second voltage across a combination of the two resistors. The measured voltages may be converted to a resistance ratio and compared to an expected value. In another embodiment, the resistance bridge measurement circuit may be configured to measure a third voltage across the other of the two resistors and a fourth voltage across a combination of the two resistors. The measured voltages may be converted to corresponding resistance ratios, summed and compared to an expected value.</p> |
