SI pressure sensor chip is a high-precision, high-reliability bridge sensor signal conditioning chip with fast response characteristics, suitable for various applications such as automotive, industrial, medical, and home appliances. The chip integrates a programmable low-noise instrumentation amplifier, a low-power 24-bit ADC, an on-chip DSP for compensation and calibration, and a high-precision DAC to achieve analog voltage output.

This chip integrates a high-precision temperature sensor and supports various off-chip temperature sensing devices (thermometers, diodes, etc.). Combined with an on-chip rewritable MTP, the chip enables digital calibration and compensation of sensor sensitivity, zero bias, nonlinearity, and temperature drift. The chip supports OWI-configured analog outputs, including isobaric and ratio output modes, and also supports clamping and self-diagnostic functions. The chip is available in a reliable SOIC-8 package or wafer, and calibration kits are provided for batch calibration.
