欢应来电洽谈NJM2902的相关信息!

          NJM2902 包括 四独立高赢利操作放大器那是设计为 唯一供应操作。从分裂电源的Operation也是可能的，并且低功率供应流失是巨大的独立power电源电压。与电路将经营在各种各样的电源电压的双重供应的Used。 然而，很多天桥畸变 可以 发生 与 装载 地面。 外在消耗电流电阻器对对意志减少天桥畸变。 如果装载指挥被结合研，没有天桥畸变问题在唯一供应操作

          NJM2902，在它的静态状态(没有和产品情况)，当设计， QU被偏心由恒定的潮流(划分射线)， QL停留。While使用与两电源方式，天桥distortion也许立即发生，当QL。There也许是盒，当应用音频放大器的signals，不仅畸变，而且卓越地变窄的明显的频率带宽。It比装载潮流是可调整的，特别是当使用电源方式，经常使用与在QU的更高的潮流(包括反馈潮流)时，然后联络下拉的抵抗者RP在产品和GND别针之间的部分。

QUAD SINGLE-SUPPLY OPERATIONAL AMPLIFIER

■ GENERAL DESCRIPTION                                                      ■ PACKAGE OUTLINE

The   NJM2902   consists   of   four   independent   high-gain operational   amplifiers   that  are   designed   for   single-supply operation.

Operation from split power supplies is also possible and the low power supply drain is independent of the magnitude of the

power supply voltage.

Used with a dual supply the circuit will operate over a wide range of supply voltages. However, a large amount of crossover distortion   may   occur   with   loads   to   ground.   An   external current-sinking  resistor  to-VS  will  reduce  crossover  distortion. There  is  no  crossover  distortion  problem  in  single-supply operation if the load is direct-coupled to ground.
