【产品】双/四通道COMS轨到轨输入输出微功率运算放大器,通道电流仅60uA
ISL28288/ISL28488是Intersil推出的一款双/四通道COMS轨到轨输入、输出微功率运算放大器,经典电路如图1所示。该运放可单电源和双电源供电,若单电源供电,电压范围为(2.4V-5.5V),若双电源供电,电压范围为(±1.2V-±2.75V),每个通道电流都低至60μA,这种低功耗和精密性能的组合使得这些器件适用于太阳能和电池电源应用。
图1 ISL28288/ISL28488经典应用电路
ISL28288/ISL28488具有输入范围增强电路(IREC),使输入电压在比V+高10%以及比V-低100mV的情况下,能够保持CMRR性能。运算在实现轨到轨输入不会牺牲重要的精度规格和降低失真性能,其输入失调电压在整个共模输入范围内表现出平滑的行为。同时运放内部有一对互补MOSFET器件用于实现轨到轨输出,NMOS使输出沿负方向摆动;PMOS使输出以正方向摆动。
ISL28288/ISL28488带输入保护,输入端内部集成了对电源正负极的ESD保护管,将输入电压钳位,同时输入端正负极内部也集成了一对背对背二极管,设计上保证差分输入不超过0.5V。如图2所示。
图2 输入端内部集成ESD保护管
ISL28288和ISL28488各两种封装,如图3所示。该运放在满足优异的直流精度,交流性能,噪声和输出驱动规格的同时,可以获得最小的电源电流,10 Ld MSOP封装ISL28288包含掉电使能引脚EN,可在禁用状态下将电源电流降至通常小于4μA。
