:
Analog circuit settling time for stable operation.
Analog reference circuits VREF & IREF start up and
configured output reference voltage is provided at VOUT
pin.
Clock count start
Analog circuit startup
Pressure judge circuit not in operation
SV initial operation (ST not in operation)
VP&VN pin fixed to 1/2*VS; given value output to VOUT
Self-diagnostic circuit operation & idling
Back to normal operation on completing self-diagnosis in
50 CLK.
Analog circuit startup
Pressure judge circuit not in operation
STV initial operation
Output pressure (VP-VN=0V) to VOUT
:(Same as operation after ST3 in 3.1 Normal Operation
Timing)
