Abstract
Described is a smart pressure sensor that can be calibrated and compensated for temperature effects by its digitally programmable on-chip electronics, without the need for additional external components or laser trimming of on-chip thin film resistors. Programming is done via a dual-line connection and a serial port by means of a PC. A program developed for this purpose determines from a simple test the optimum bit combinations for the six programmable parameters that are stored in a 30-bit static on-chip shift register.
