MAX951ESA+T 产品描述
微功率运算放大器,比较器,并在8引脚封装的参考MAX951 MAX954的功能组合。在MAX951和MAX952比较器的反相输入连接到内部1.2V±2%的带隙基准。 MAX953和MAX954提供无需内部参考。 MAX951/MAX952经营从单一2.7V至7V一个典型的供应7μA电流供应,而MAX953/MAX954操作与5μA典型电源电流从2.4V至7V。两个运算放大器和比较器功能的共模输入电压范围扩展1.6V内从负供电轨的积极铁路,以及摆动的轨到轨输出阶段。
在MAX951/MAX953的内部补偿运算放大器是单位增益稳定,而在MAX952/MAX954功能125kHz的典型带宽的运算放大器,66V/ms摆率,稳定和10V / V或更高的收益。这些运算放大器具有独特的输出级,使他们与超低电源电流,同时保持负载条件下的线性。此外,他们已经设计,展示良好的直流特性,在其整个工作温度范围,最大限度地减少输入提到的错误。
这些设备比较器输出级的来源,尽可能40毫安。比较消除电源故障通常发生时改变逻辑状态,最大限度地减少寄生反馈,使设备更容易使用。此外,他们还包含±3mV的内部迟滞,以确保干净的输出切换,甚至滞销的输入信号。
