说明

OPA836 和 OPA2836 器件 (OPAx836) 为单通道和双通道超低功耗、轨至轨输出、负电源轨输入、电压反馈 (VFB) 运算放大器,依设计可由 2.5V 至 5.5V 范围内的单电源或者 ±1.25V 至 ±2.75V 范围内的双电源供电运行。这些轨至轨放大器每通道仅消耗 1mA 的电流,单位增益带宽为 205MHz,功耗/性能比处于先进水平。

OPA836 和 OPA2836 器件同时拥有低功耗特性和出色的高频性能,并且可提供其他同类器件所无法达到的性能/功耗比,因此非常适合注重功耗的电池供电类便携式应用。这些器件还具有节能模式,可将电流降至 1.5μA 以下,这对于电池供电类应用中的高频放大器而言是极具吸引力的解决方案。

OPA836 RUN 封装选件包含集成的增益设置电阻器,因此可在印刷电路板上实现超小的尺寸(约 2.00mm × 2.00mm)。通过在 PCB 上添加电路迹线,可实现 +1、–1、–1.33、+2、+2.33、–3、+4、–4、+5、–5.33、+6.33、–7、+8 的增益和 –0.1429、–0.1875、–0.25、–0.33、–0.75 的反相衰减。有关详细信息,请参见Table 9-1Table 9-2

OPA836 和 OPA2836 器件在 –40°C 至 +125°C 的扩展工业温度范围内运行。
