continues the discussion about proper turn-On sequence for your 2W amplifier IC? To put the explanation into words might be: several delay stages depend on successfully getting through each previous delay stage. The first delay is applied to the positive supply. When successfully detected, another delay begins while the negative supply becomes stable. When that is successful, another delay begins (C10 does the task at this point). Then both supplies are passed through to the rest of the circuit.<br /> <br /> It's not obvious from looking at the schematic but it performs some back-and-forth notification between the positive and negative sides. It's not easy to see there's a teeter-totter effect at work causing the different delay functions. Adjustments are necessary to many components, before the output timing occurs as you desire.<br /> <br /> I can believe this part of the project is important because the turn-On sequence should be accomplished before any signal (any voltage) arrives at the input. Practically all advice says the input(s) at any IC should not exceed 1/2 V beyond supply rails. This means you should not input a signal while the IC is Off. If I'd kept this in mind I believe it would have saved some of my destroyed IC's.</div> </div> <div class="js-selectToQuoteEnd"> </div> </article> </div> </div> <footer class="message-footer"> <div

Some questions are best answered by the designer. And some problems stand out. Node 'e' is where two op amps output directly to each other. Perhaps they have high output impedance nevertheless it's not usual electronics practice.<br /> <br /> At left of the op amps are Wheatstone bridges, one for positive, one for negative polarity. Conceivably the time-delay capacitors truly accomplish their purpose. <br /> <br /> I've been wondering whether the circuit can be distilled into simpler topology by using IC's. Its operation would become easier to grasp. For instance logic gates have their built-in threshold of supplyV/2 where they change state. Optocouplers can ease the communication between positive and negative polarities.</div> </div> <div class="js-selectToQuoteEnd"> </div> </article> </div> </div> <footer class="message-footer"> <div

Normally Load Regulation error on linear regulators is 1%, meaning the driver is >=100 times lower than the load R at max current. If your load current increases rapidly while the transistor is turning on and both now are lowering resistance, or you ar driving a low ESR gate capacitance there may be a large initial error in one supply (read as delay) which has more capacitance in the load. But logic switching design is when DC supplies are; stable, "Good V" or OK, and < 1% load reg. error expected so a fast logic transition drives the output (unless there is a reason not to). It is rather undefined since your load is undefined in terms of mA and C (nF)</div> </div> <div class="js-selectToQuoteEnd"> </div> </article> </div> <div class="message-lastEdit"> Last edited: <time
