As seen in Sections "2.1) VOUT pin output voltage stabilization time" and "2.2) Noise Reduction Effect with
Band Limitation", the VO pin external capacitance value should be reduced to decrease the measurement
time. The VO pin external capacitance value should be larger to reduce the noise.
On determining the VO pin external capacitance value, various conditions should be thoroughly reviewed
according to the application requirements.
3) Pressure Threshold Detection Operation at Power-Up
Note that pressure threshold detectors operate at power up.
VOUT pin output voltage is settled down based on the time constant determined by the internal resistance
146kΩ and VO pin external capacitance Cap value (see 2) Finding the VOUT and VO Pins External
Capacitance (Cap)). Note that errors may be detected during the time in which VOUT pin output is not
settled down to the voltage required according to the pressure applied.
