本文介绍了如何使用NE555制作负电压产生电路,电路简单,取材容易,唯一缺点是输出电流小,输出电压不稳压,可在要求不高的场合使用。
This simple circuit is a good solution to the powering a dual supply op amp from a single battery problem. The circuit simply takes a positive voltage and inverts it. It uses only one 555 timer and a few other passive components, so it doesn't add much in the way of size and cost to a project.
