摘　　要：随着现代科学与技术的高速发展,高精度传感器的应用日趋成熟。MAX1452作为一种高度集成的模拟传感器信号处理器,具有16引脚SSOP封装、全模拟信号通道、低功耗、温度范围宽等特点,可用于硅压阻压力传感器的数字补偿。硅压阻压力传感器输出的信号经过MAX1452校准补偿版输出模拟信号,再经过A/D转换器输出数字信号,在这个过程中,MAX1452全模拟信号通道没有引入量化噪声,利用16位DAC实现数字化校正,16位DAC对信号的偏移量和跨度进行校准,实现硅压阻压力传感器的数字补偿。With the highs-peed development in the modern science and technology, the application of high accuracy senors is becoming mature, The MAX1452 is a highly integrated analog-sensor signal processor optimized for digital compensation method of silicon piezoresistive pressure sensors, The MAX1452 is packaged with 16-pin SSOP, The MAX1452 provides a fully analog signal path, low power consumption and awide temperature range, The MAX1452 temperature circuit compensation can transform the signal of silicon piezoresistive pressure sensors intothe analog-signal, and then the A/ D convertor changes it into digital-signal, In the whole process, the fully analog signal path introduces noquantization 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 sensors,
