I/O timing chart
Note
The time to start re-zero operation differs, depending on the timing of the re-zero input:
a. To enter re-zero operation without data update
b. To enter re-zero operation after data update
In addition, the time to complete re-zero operation is not constant due to ambient conditions
such as external disturbance or vibration.
Using the status signal, confirm that RE-ZERO input is accepted or re-zero operation is complete.
“BUSY input ON” is the condition that pin 7 is connected to input signal GND (pin 3).
"RE-ZERO input ON" is the condition that pin 9 is connected to input signal GND (pin 3).
T int Data output interval Approx. 100 msec (Approx. 200 msec when the
data refresh rate is 5 times/second.)
T str Strobe pulse width Approx. 70 msec (Approx. 170 msec when the
data refresh rate is 5 times/second.)
T st Data setup 10 μsec or less
Data refresh rate 1 μsec or less
“Switch input ON” is the condition that is connected to input signal GND (pin 3).
T on, T off : 100 m sec or longer
