<550 <550 µs OPERATING TEMPERATURE RANGE −40 +125 −40 +125 °C 1 All minimum and maximum specifications are guaranteed. Typical specifications may not be guaranteed. 2 Cross axis sensitivity is defined as the coupling of excitation along a perpendicular axis onto the measured axis output. 3 Includes package hysteresis from 25°C. 4 Difference between maximum and minimum values in temperature range. 5 Specified as frequency range that is within a deviation range relative to dc sensitivity, range is limited by an increase in response due to response gain at the sensor resonant frequency. 6 For capacitive loads larger than 100 pF, an external series resistor must be connected (minimum 8 kΩ). The output capacitance must not exceed 22 nF. 7 Measured time difference from the instant VDD reaches half its value to the instant at which the output settles to 1% of its final value.
