Precision polarity switching circuit by conventional elements

Posted on Mar 28, 2007

Because the loop gain of the amplifier OP depends mainly on the dry input resistor and feedback resistor ratio, so the resistance error, an error occurs opening will be a corre

sponding gain in order to get more accuracy caused by four, you need high-precision resistors for o narrow range of VRI variable resistor Rs, ugly whose resistance Rl, R2 1/100, this kind of deviation can be compensated resistance, RL is actually g. 9kQ, Rz is 10.1 kQ, this worst-case scenario is very small, so VRi adjustable range of disabilities 1% is enough.
