八触控 BCD 输出 IC

PT8028是一款电容式触摸控制ASIC，支持8通道触摸输入，二进制BCD编码和有效按键指示输出。算法带有自补偿功能，具有低功耗、高抗干扰、宽工作电压范围、高穿透力的突出优势。 - 工作电压范围：2.4~5.5V\n- 工作电流：3mA（正常模式）；20uA（低功耗模式）@VDD=5V&CMOD=10nF\n- 8通道触摸输入\n- 二进制BCD编码输出（上电D2~D0=111）\n- 当前触摸按键有效后，BCD编码输出状态会维持到下次按键才改变\n- 提供按键承认输出，有按键时输出低电平，无按键输出高电平\n- 算法可自补偿修正触摸通道差异或走线长短不一致情况\n- CMOD脚外接电容可调节灵敏度，电容越大灵敏度越高\n- 具有防水功能，当水漫或成片水珠覆盖在触摸面板时，按键仍可有效判别\n- 内置稳压源、上电复位和低压复位等硬件模块\n- 内置实时环境自适应、高效;
