说明

OPAx863 器件是单位增益稳定的低功耗、轨至轨输入/输出、电压反馈运算放大器,需在 2.7V 至 12.6V 的电源电压范围内运行。OPAx863 器件每通道仅消耗 700µA 的电流,提供的增益带宽积为 50MHz、压摆率为 105V/µs,电压噪声密度为 5.9nV/√ Hz

具有 2.7V 电源电压的轨至轨输入级在便携式电池供电型应用中非常有用。差分输入级可在整个输入共模电压范围内很好地适应增益带宽积和噪声,从而在宽输入动态范围内实现出色的性能。OPA863 具有断电 (PD) 模式,PD 静态电流为 1.4µA(最大值),并在 6.5µs(典型值)之内开启或关闭。

OPAx863 器件包括过载功率限制功能,可限制输出饱和时静态电流的增加,从而避免电池供电型系统中出现严重的过度损耗。输出级具有短路保护,使得该器件成为坚固耐用的通用放大器。
