■ Description of Operation Timing Status (pressure detection circuit effective)

Note1) Only operation in the quasi 2nd order correction mode by piecewise linear approximation

Note2) Only operation in the Fs = 0.83kHz mode

State No. CLK Operations

Start Up 00 It is the time until analog circuits operate stably.

Analog reference circuits as VREF, IREF, etc. start up and

adjusted output reference voltage (VSS or VDD or

0.5*VDD) is output from the VOUT pin.

PU0 01 CLK = 30 Clock count start

Analog circuits startup

02 CLK = 0 or 5

Ta = 25

STV 20 CLK = 30 STV circuits operation

MSR 30 CLK = 30 Result of pressure correction is output from VOUT pin.

Idel 40 CLK = 0 or 505 Idling

With Fs = 8.33kHz, no idling and in continuous operation.
