AN-581: Biasing and Decoupling Op Amps in Single Supply
Figure 1. A Potentially Unstable Single Supply Op Amp Circuit. This simple circuit has some serious limitations. One is that the op amp''s power supply rejection is almost entirely gone, as any change in supply voltage will directly change the V S /2 biasing voltage set by the resistor divider. Power Supply Rejection (PSR) is a very important (and frequently overlooked) op amp …

Dual Supply From Single Battery Source
Dual-voltage power supply is required especially for powering the op-amps and some of the instrumentation amplifiers. A few low-power audio pre-amplifiers also use dual-voltage supply. This circuit provides both +9V as well as -9V supply from a single 9V battery. It consists of timer IC NE555 (IC1), negative-voltage regulator IC 7909 (IC2) and ...

An alternating current (AC) power supply can either be single-phase or three-phase: A three-phase power supply is composed of three conductors, called lines, which each carry an alternating current (AC) of the same frequency and voltage amplitude, but with a relative phase difference of 120°, or one-third of a cycle (see Figure 4). These ...

Make a symmetrical power supply with a single power source
To keep the project simple, I wanted to power it with a single battery. I need to power the strain gauge with 10V, so my battery is going to be more than that (probably regulated by some sort of linear regulator) to avoid ripples in strain gauge measurement. I need a symmetrical power supply for the strain gauge because the output ...

For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. Typical values for bipolar converters like this are 100k-1M for the resistors and 47uf to 4700uf depending on the current draw of your circuit.

Dual Power Supply From Single (+-12V/+-1A From Single 15V)
Today I will write about how to make a dual supply -+12V (or other) from a single supply source. It''s nothing special, but when I tried to search the internet, I found almost no practical construction. The advantage of this power supply is that you can load only one loop and the device will work correctly. You can use a 24 volt without using a ...
