求翻译：运放的供电方式分双电源供电与单电源供电两种。对于双电源供电运放，其输出可在零电压两侧变化，在差动输入电压为零时输出也可置零。采用单电源供电的运放，输出在电源与地之间的某一范围变化。是什么意思？

Op amp power supply dual power supply points with a single supply two. For dual-supply op amp, the output voltage at both sides of zero change in the differential input voltage is zero, the output can be set to zero. Single supply op amp, the output power and ground in a range between changes.

Trading on the power supply double-power supply with two single power supply. The case of dual-power supply operation, its output can be placed on the zero-voltage side, change the differential input voltage is zero output could also be put 0. uses a single power supply, the output of operational am

Transports puts like the chart to have two input end a (opposition input end), b (synchronism input end) and out-port o.Also is called separately the reverse input end non-reverse input end and the out-port.When voltage U- adds in a end and the public end (the public end is the voltage for the zero

Op amp power supply dual supply and single supply two kinds. For a dual-power operational amplifier, the output at zero voltage changes on both sides, the differential input voltage is zero output can also be zero. Single-supply operational amplifier, the output between the power supply and a range
