The NSA2300 is a highly integrated 24-bit sensor conditioner for applications of high precision low frequency measurement such as pressure transducer, weight scale. It can provide fully calibration for the sensor inherent temperature drift and non-linearity with a high resolution internal or external temperature sensor. The chip incorporates an in-amp, a buffer and a 24-bit sigma delta modulator followed by a calibration DSP. With wide gain and OSR range, the NSA831 could be suitable for variance sensors. One-time- programmable fuses are used to store the calibration coefficients for on-chip calibration calculations. SPI and I2C interfaces are supported for serial communication. 超小体积，高精度压力温度传感器
