MAX1455：低成本、汽车传感器信号调理器
MAX1455为一个高集成度的汽车模拟传感器信号处理器，用于阻性传感器。MAX1455具有放大、校准及温度补偿功能，可使全部性能接近传感器固有的性能。利用集成的16位数模转换器(DAC)进行数字调理控制，整个模拟通道不会在输出信号上引入量化噪音。失调和满量程范围也通过16位DAC得到校准，允许传感器互换。 MAX1455包括一个可编程的传感器激励器、16级增益可编程放大器(PGA)、768字节(6144位)的内置EEPROM、四路16位DAC、一路附加运放以及一个内部温度传感器。除了失调及满量程补偿，MAX1455还提供独特的温度补偿方案，可提供灵活的温度重新标定，降低了测试成本。 MAX1455提供裸片、16引脚SSOP和TSSOP封装。
