| 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 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. |
