Optional Flip inverter circuit

Posted on Mar 28, 2007

Use the circuit shown we can reverse or flip the switch amplification without inversion. Voltage gain depending on the position of the switch. This may be +1 or -1. Changing circuit has two versions, A and B. I personally prefer B

type, because there is no non-inverting input voltage level is uncertain at the moment. In one version, when the switch is flipped, with the non-inverting input is temporary floating, which may lead to unpredictable voltage indu1ced through the wiring of the switch, so that the hard click or murmur. This phase inverter circuit provides a polarity control is useful, for example, many channel audio power amplifier supplied (or queen Only) This function flips stage situation with a speaker wiring or installation error, because it is easier push a switch, instead of re-connecting cable.
