Abstract :
An all-silicon, bipolar, two-chip integrated pressure transducer was developed. This device uses a piezoresistive pressure cell and a single-signal conditioning integrated circuit. No external compensation components are required for this circuit board mount device. This device uses a unique temperature-compensation circuit differing in basic concept from that used in previous attempts at developing such a device. No special TC resistors are required. The pressure-sensing cell has digital adjustment capabilities for zeroing the cell output.<>
