With the modern science and technology high speed developing, the application of high accuracy senor is becoming mature. The MAX1452 is a highly integrated analog-sensor signal processor optimized for digital compensation method of silicon piezoresistive pressure sensor. The MAX1452 is packaged 16-pin SSOP. The MAX1452 provides fully analog signal path, low power consumption and wide-range temperature. The MAX1452 temperature circuit compensation can transforms the signal of silicon piezoresistive pressure sensor into the analog-signal, than the A/D convertor change it into digital-signal. In the whole process, the fully analog signal path introduces no quantization noise in the output signal while enabling digitally controlled trimming with the integrated 16-bit DACS. Offset and span are calibrated using 16-bit DACS, allowing the digital compensation of silicon piezoresistive pressure sensor.
