skeptic2 said:Yes it can still function. The +V remains +V, the ground becomes -V and you need to create a pseudo ground in place of the ground. This is usually done with a voltage divider to create a voltage halfway between +V and ground. A relatively large capacitor is usually connected between the junction of the voltage divider resistors and ground, or +V or both.
Abstr7ct said:also, if voltage divider is used, wouldn't that consume power from the power supply?
skeptic2 said:Yes it will, and if you want a low impedance DC pseudo-ground, it will draw substantial power from the power supply. If you get into that situation you may be able to accomplish the same effect with a high resistance divider and an op amp buffer.
A google search will turn up plenty of information, e.g., http://www.eng.yale.edu/ee-labs/morse/compo/sloa058.pdf[/color]weitao said:Normally the connection of supply voltage is +-V but now is +V and ground.
What happen if Op-amp (ua741) with only positive supply voltage? The op-amp still function?
An op-amp (operational amplifier) is an electronic device that amplifies the difference between two input voltages. The ua741 is a specific model of op-amp. When an op-amp has only a positive supply voltage, it means that it can only accept positive input voltages and output positive voltages.
An op-amp with only positive supply voltage is often used in applications where the input and output signals are both positive. It can also be used in circuits where a negative supply voltage is not available. Additionally, it can simplify the circuit design by eliminating the need for negative voltage components.
No, an op-amp with only positive supply voltage cannot be used in circuits with negative input or output voltages. It is designed to only work with positive voltages, so using it in a circuit with negative voltages can damage the op-amp and affect the accuracy of the circuit's output.
An op-amp with both positive and negative supply voltages has a wider input and output voltage range compared to one with only positive supply voltage. This allows it to handle both positive and negative voltages and produce a more accurate output signal. Additionally, an op-amp with both supply voltages may have different internal circuitry to accommodate the negative voltage.
An op-amp with only positive supply voltage is commonly used in audio amplifiers, signal conditioning circuits, and sensor circuits. It can also be used in battery-powered devices and portable electronics where a negative supply voltage is not available. Additionally, it is often used in circuits with single-ended power supplies to simplify the design and reduce costs.
