电容式触摸传感器专用可编程控制器

AD7143是具有片内环境校准功能的集成式电容-数字转换器（CDC），可用于需要采用新型用户输入法的系统。AD7143可与外部电容式传感器接口，从而实现电容按钮、滚动条和滚轮等功能。 \n\n CDC有8个输入通道，通过一个开关矩阵与一个16位、250 kHz sigma-delta （Σ-Δ）电容-数字转换器相连。该CDC能够感知外部传感器的电容变化，并借助此信息来记录传感器激活事件。外部传感器既可配置成一系列按钮，也可配置成一个滚动条或滚轮，或者各类传感器的组合。通过对寄存器进行编程，用户可完全控制CDC设置。高分辨率传感器要求在主机处理器上运行软件。\n\n AD71 • 可编程的电容-数字转换器\n25 ms的更新速率（最大序列长度时）\n分辨率优于1 fF\n8个电容式传感器输入通道\n无需使用外部RC调谐元件\n• 自动转换定序器\n片内自动校准逻辑\n自动补偿环境变化\n自适应式阈值和灵敏度水平\n• 用片内RAM存储校准数据\n• I2C® 兼容型串行接口\n• 串行接口专用独立VDRIVE电平\n• 主机控制器中断输出\n• 16引脚、4 mm × 4 mm LFCSP-VQ封装\n• 2.6 V至3.6 V的工作电压\n• 低工作电流\n全功耗模式：不足1 mA\n低功耗模式：50 µA;
