AP3 series

The AP3 pressure sensor series is composed of a silicon piezoresistive pressure sensing chip and a signal conditioning integrated circuit. The signal conditioning IC does not have A/D and D/A converter in a gain amplifier. Therefore the AP3 series can provide full analog amplified and temperature compensated output. Moreover the amplification circuit is designed with low noise output. As a unique function, the AP3 series has Single Point Pressure Threshold Detection. Analog output and threshold voltage are supplied to an internal comparator that compares two voltages and outputs a comparison result as digital output.
