OPA836和OPA2836采用业界领先的BiCom-3x(SiGe互补双极型)工艺制造,是单通道和双通道超低功耗,轨道到轨输出,负电源轨输入,电压反馈运算放大器,专为在2.5V至5.5V的单电源范围和±1.25V至±2.75V的双电源范围内的运行而设计。每个通道的电流消耗仅为1mA,并具有205MHz的单位增益带宽,这些放大器为轨到轨放大器设定了一个业界领先水平的功耗 - 性能比。
对于功耗十分重要的电池供电型便携式应用而言,OPA836和OPA2836的低功耗及高频性能为设计人员提供了其他器件所无法获得的性能与功耗比。与流耗小于1.5μA的节能模式组合在一起,此器件为电池供电应用中的高频放大器提供了一款极具吸引力的解决方案。
OPA836和OPA2836提供以下封装选项:OPA836单通道:小外形尺寸晶体管(SOT)23-6(DBV) ,和具有集成增益阻器的10引脚极薄四方扁平无引线(WQFN)(RUN)封装.OPA2836双通道:小外形尺寸集成电路(SOIC)-8(D),超薄型小外形尺寸(VSSOP)(MSOP) -10(DGS),10引脚极薄四方扁平无引线(WQFN)(RUN)和10引脚超薄四方扁平无引线(UQFN)(RMC)封装。的第二段
OPA836 RUN封装选项包括在一块印刷电路板上最小可能封装的集成增益设置电阻器(≈2mmx 2mm)。通过在印刷电路板(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的反向衰减。更多细节请参见部分。
该器件的特色是可在-40°C至125°C的扩展工业温度范围内运行。
