双极性/JFET双通道音频运算放大器

OP275是一款采用巴特勒放大器前端的放大器。这种新型前端设计集双极性与JFET晶体管于一体，兼有双极性晶体管的精度和低噪声性能，以及JFET晶体管的速度和音质。总谐波失真+噪声(THD+N)与以前的音频放大器相当，但电源电流低得多。\n\n l/f转折频率低于6 Hz，因而噪声密度响应很平坦。无论在30 Hz还是1 kHz测量噪声，其值仅为6 nV/√Hz。即使在需要较大输出摆幅时，输入级的JFET部分也能使OP275具有高压摆率，从而保持低失真。该器件的压摆率为22 V/µs，在所有标准音频放大器中最快。最可喜的是，实现这种低噪声和高速性能所耗用的电源电流不到5 mA，低于所有标 • 出色的声学特性 \n\n• 低噪声： 6 nV/√Hz \n\n• 低失真：0.0006%\n\n• 高压摆率： 22 V/µs \n\n• 宽带宽： 9 MHz \n\n• 低电源电流： 5 mA \n\n• 低失调电压： 1 mV \n\n• 低失调电流： 2 nA \n\n• 单位增益稳定 \n\n• SOIC-8封装 \n\n• PDIP-8封装;
