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. A thorough search could turn up many more. this is not a good general practice. You should always check the datasheet before doing this. WebUnused analog signal inputs should usually be connected to a dc potential but may sometimes need to be grounded at ac only by a capacitor—RTFDS 8. In many cases this dc potential may be a power supply or ground, but for reasons that are discussed in more detail in RAQ 46 3, amplifier inputs often need different treatment. WebIt is particularly important to consider unused logic inputs, as some must be tied to Logic-1 when unused.
