数据: 1.8V, 1μA max, Zerø-Crossover RAIL-TO-RAIL I/O OPERATIONAL AMPLIFIER 数据表
OPA369和OPA2369是TexasInstruments的超低功耗,低电压运算放大器,专为电池供电应用而设计。
OPAx369采用低至1.8V的电源供电,具有真正的轨到轨操作,适用于各种应用。 zerø-crossover 功能解决了输入交叉失真的问题,这种问题在低压(<3V),轨到轨输入应用中变得非常突出。
除了微型尺寸封装和极低的静态电流,OPAx369具有12kHz带宽,低失调漂移(1.75μV/°C,最大值)和低噪声3.6μV PP (0.1 Hz至10Hz)。
OPA369(单一版本)采用SC70-5封装。 OPA2369(双版本)采用MSOP-8和SOT23-8封装。
