Single Wire Analog Output Sensor Architecture

A analog integrated sensor device has an interface with only a single ground line and a single signal line configured to receive power and output an analog value. A power capacitor is coupled between the ground line and the single signal line. An analog sensor circuitry is operable to be powered by...

Summary:A analog integrated sensor device has an interface with only a single ground line and a single signal line configured to receive power and output an analog value. A power capacitor is coupled between the ground line and the single signal line. An analog sensor circuitry is operable to be powered by the power capacitor and further operable to output an analog output signal on the single signal line once the power capacitor has bee charged sufficiently.
