【产品】单电源电压2.5~36V的四路差分比较器LM2901A,输入偏置电流4nA typ.
思瑞浦推出的四路差分比较器LM2901A系列由在一个单片衬底上的双路/四路比较器组成,可独立单电源或双电源供电。即使在单电源运行时,共模输入电压范围也包括‘地’电平。低电源电流消耗使其适用于电池供电。该系列比较器可直接连接TTL和CMOS接口,电流消耗与电源电压无关。其输出可连接至其他集电极开路输出,以实现线与逻辑关系。
思瑞浦LM2901A为四通道版本,可选SOP14封装。该系列所有比较器工作温度范围为 -40℃至+125℃。
产品特征
宽单电源电压范围或双电源供电:+2.5V至+36V或±1.25V至±18V

低输入偏置电流:4nA typ.
低失调电压:最大±3.0mV
输入共模电压范围包括“地”电平
内部差分输入电压范围等于电源电压
输出兼容TTL, DTL, ECL, MOS, CMOS
输入端的ESD钳位增强了比较器耐用性,且不影响其性能
低输出饱和电压
工作温度范围-40℃至+125℃
ESD额定值:4KV-HBM, 2KV-CDM
高性能引脚兼容339、339、2903、2901系列产品
产品应用
高速线路接收机或数字线路接收机
高速采样电路
峰值检测器和过零检测器
阈值检测器或阈值鉴别器

热性能信息
绝对最大额定值(注1)
注1:超过以下列出的绝对最大额定值时可能会导致设备永久性损坏。长期暴露在任何绝对最大额定值条件下,可能会影响设备可靠性和使用寿命。暴露在任一绝对最大额定值的条件下,可能会影响设备的可靠性和使用寿命。
注2:输入端通过ESD二极管连接到每个电源进行保护。如果输入电压超出电源500mV以上,输入电流应限制在10mA以下。
注3:可能需要一个散热器来保持结温低于绝对最大额定值。这取决于电源电压以及放大器短路数量。热阻随连接到封装的PC板金属量而变化。指定值针对连接到引线的短线。
