Notes:
1. Reference conditions (unless otherwise noted): supply voltage, V
S=5.0 ±0.01 Vdc, Ta=25 °C [77 °F].
2. Read operation: Start, Slave Address, R/W =1, Data Byte 1 (MSB), Ackn Bit, Data Byte 2 (LSB). The output is corrected pressure as unsigned 12 bits. Slave Address
is F0h. Acknowledge Bit - pull data line LOW, master generates an extra clock pulse for this purpose.
3. Span is the algebraic difference between the output voltage at the specified high pressure and the output at lowest pressure. Span is ratiometric to the supply voltage.
4. Accuracy is the combined errors from offset and span calibration, linearity, pressure hysteresis, and temperature effects. Calibration errors include the deviation of
offset and full scale from nominal values Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point within
the operating pressure range for increasing and decreasing pressure and temperature.
5. Response time for 0 PSI to full scale pressure step change, 10% to 90% rise time.
6. Sensor output when maximum positive pressure is applied on the back side (P2) or the front side (P1) of the sensing element.
