resistance
1) 200 measurements in sequence, bandwidth limited to 40kHz
2) More details in section “Timing Properties” on Page 16
3) The maximum response time considers a maximal value of 100nF for the output blocking capacitor C₂ and a maximum
pressure pulse equivalent 4.0V output change
4) In the event of a broken wire (broken VDD line or broken GND line), the output changes to certain voltage levels within the
broken wire response time. The OBD ranges are determined by the application circuitry
