Digital Output
Semiconductor Pressure Sensor
Description
The AG4 pressure sensor series 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
digital data that is proportional with the applied
pressure. The AG4 series measures gauge pressure.
