#71411 - RE: Input signals to A/D Responding to: ???'s previous message |
As always thanks Kai.
When 24V is applied across +I and -I what is the voltage drop across the LM317? Would that eliminate the possibility of using the surface mount SOT-223 package? With the 2.5V drop across the the LM317 how does that effect the compliant voltage of the current sources? If the voltage sources are specified at +12 - 28 does that mean that +15 should be the minimum voltage when using the LM317? The 30V transorb on the +I, -I is it's purpose to block out any short duration voltage spikes that could damage the LM317? Finally can you explain the operation of diodes LL101A and LL4148 around the 89C52? |
