RECOMMENDED OPERATING CONDITIONS
NOTES
1) Under the assumption of one conversion every second. Conversion means either a pressure or a
2) During conversion the sensor will be switched on and off in order to reduce power consumption; the total on
3) This value can be reduced by switching off MCLK while MS5540C is in standby mode.
4) It is strongly recommended that a crystal oscillator be used because the device is sensitive to clock jitter. A
