OPAx377-Q1 系列运算放大器属于高带宽 CMOS 放大器,同时拥有超低噪声、低输入偏置电流和低偏移电压特性,静态工作电流低至 0.76mA(典型值)。
OPAx377-Q1 运放针对低电压、单电源应用进行了 优化。其交流和直流性能都非常出色,非常适合 诸如小信号调节、音频和有源滤波器等各类应用。此外,该系列器件还具有较宽的电源范围及优异的电源抑制比 (PSRR),因此对于不经过稳压而直接由电池供电运行的 应用 而言极具吸引力。
OPA377-Q1 采用 SOT23-5 封装。OPA2377-Q1(双通道版本)采用微型小外形尺寸 (MSOP)-8 封装,OPA4377-Q1(四通道版本)采用 TSSOP-14 封装。所有器件版本的额定工作温度范围均为 -40°C 至 +125°C。
