The KP276A1201 device is fully calibrated on delivery. The sensor has a linear transfer function between the applied pressure and the digital output signal. 4088 3896 3000 [LSB] Zoom 2000 Output signal 1000 193 1 0 10 40 80 120 160 200 240 280 320 360 400 440 Pressure [kPa] Operating pressure range
Figure 3 Pressure transfer function Clamping
The output signal for pressure is limited internally to clamping level low (output code 1) and clamping level high (output code 4088).
