1. General
This document describes the specifications of Fujikura Pressure Sensors, APB2 series.
2. Principle
Fujikura Pressure Sensor is composed of a silicon piezoresistive pressure sensing chip and a signal
conditioning integrated circuit. The low-level signal from the sensing chip is amplified, temperature
compensated, calibrated, and finally converted to a high-level output signal that is proportional to the
applied pressure.

Notes:
*1) Output voltage (Vout) is not perfectly ratio-metric with Supply voltage (VDD).
*2) Gauge pressure is defined as the difference between applied pressure to the pressure port and an
atmospheric pressure of the device.
*3) Ensure the pressure media contains no particulates. The device is not compatible with liquids.
*4) Pressure range is defined as the measurable pressure range of the device. Do not expose intentionally
beyond minimum Popt and maximum Popt.
*5) Please also refer to Chapter 0 Transfer Function.
*6) Do not wet the device with dew.
*7) Dielectric strength is defined as the leakage current between all pins and the package with AC 500 V, 1
minute.
*8) Insulation resistance is defined as the resistance value between all pins and the package with DC 500 V.

Notes:
*1) Offset voltage (Voff) is defined as the output voltage at minimum Popt. In case of 050KV and 100KV, Offset
voltage (Voff) is defined as the output voltage of maximum Popt.
*2) Offset error is calibration error of Offset voltage (Voff) at production. It does not include Long term offset
drift. It would be suggested that applications have Auto-zeroing function.
*3) Full scale voltage (Vfs) is defined as the output voltage at maximum Popt. In case of 050KV and 100KV, Full
scale voltage (Vfs) is defined as the output voltage of minimum Popt.
*4) Output span voltage (SV) is defined as the voltage difference between Offset voltage (Voff) and Full scale
voltage (Vfs).

*5) Accuracy consists of the following:
Non-linearity
Temperature errors over the temperature range 0 to 85 degree C
Pressure hysteresis
Calibration errors of sensitivity and offset
*6) The unit of Accuracy “%FS” is defined as a percent error by Span voltage (SV).
*7) Output voltage (Vout) is generated by the internal digital to analog converter. Therefore the output voltage
has Output resolution (Vrso). Resolution in pressure is calculated as below:
Pressure resolution =
Vrso
×Pressure range (Min. to Max.)
SV
*8) Supply Current (Ic) is increased depending on the value of Load resistor (RL).
*9) Response time (tr) is defined as the time for the change in Output voltage (Vout) from 10 % to 90 % or from
90 % to10 % of its final value when the input pressure makes a step change.
Input Pressure

Final value
90 % of Final value
Output Voltage

*10) Output voltage (Vout) is sampled and held by the internal sampling / hold block. Sampling frequency (fs) is 1
kHz. The output voltage is changed stepwise every approximately 1millisecond.
