Analog Devices / Maxim Integrated 美信 MAX11300 20 端口混合信号 I/O
美信 MAX11300 在单片集成电路中集成 PIXI™、12 位、多通道模/数转换器(ADC)和 12 位、多通道、带缓冲性能的数/模转换器(DAC)。该器件提供 20 个混合信号、高压、双极性端口，可配置作为 ADC 模拟输入、DAC 模拟输出、通用输入(GPI)、通用输出(GPO)或模拟开关端子。一个内部和两个外部温度传感器分别跟踪结温和环境温度。相邻的一对端口可配置用于开漏器件逻辑电平转换器或模拟开关。PIXI 端口提供高灵活度的硬件配置，适用于 12 位混合信号应用。MAX11300 非常适合用于对模拟和数字混合功能有要求的应用。每个端口可独立配置，-10V 至 +10V 内有多达四个可选电压范围。
PIXI ports provide highly flexible hardware configuration for 12-bit mixed-signal applications. The MAX11300 is best suited for applications that demand a mixture of several analog and digital functions. Each port is individually configurable with up to four selectable voltage ranges within -10V to +10V.
