One or more embodiments are directed to a resistance bridge measurement circuit configured to perform an internal self-check. The resistance bridge measurement circuit may include two or more internal resistors. 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 measurea 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, summedand compared to an expected value.
