How to Properly Terminate an unused OP-Amp to Avoid Noise …

WebNow, when we talk specifically about an operational amplifier, the symbol for that, we use for an operational amplifier, is a triangle. It has two inputs, one is the plus input, one is the minus input, and it has an output, and it also has two power supplies to it. There's some sort of plus voltage that goes into it, and some sort of minus voltage. Web24 de fev. de 2007 · Hero999 said: I normally connect one input to +V and the other to -V and the output to nothing. Some op amps have parallel back-to-back diodes across the inputs, e.g AD706.

Working with op amps: tying down floating pins - Analog IC Tips

Web15 de set. de 2004 · For some op-amps, you might be able to connect the terminals to opposite rails, but this is not a good general practice. For example, some op-amps have diodes in place to limit the differential input voltage. These op-amps will draw a lot of current from the supply rails if you exceed the maximum differential input voltage! Web20 de jun. de 2011 · CMOS device inputs must always have a path to +V or GND, or your results may be unpredictable. If you have unused opamps in a package, connect the output of each amplifier to it's inverting (-) input, and connect the noninverting (+) input to a reference voltage that is between +V and GND or -V.
