And it is so, if R2 and R3 are not present in the circuit. You can’t do this with one 9V battery. Enric Blanco 4, 5 11 The circuit operates as a resistive voltage divider. As if they are not. Those references are not batteries.

That adds up to a minimum of 0. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Select a lower value for R1. This, of course, ignores your bias current through your LM The problem you’re encountering is that R1 is so high that it doesn’t let enough current flowing through to operate the diodes as they should.

To achieve the desired result descending resistance R1.

I’m doing a simple circuit using LM You need to drop the 10K to a lower datasueet, or use two batteries, but make sure you don’t exceed the maximum bias currents for your references.

However, at 4V voltage drop, the 10k resistor can only provide 0. Besides, from what I understand voltage across anode of D1 and cathode of D2 should be always 5V, right? I changed R2 and R3 to 47k and 22k and all works fine!

AltAir 2 Lj385z must select a value well below this. If you don’t feed them with enough current and voltage they are just resistors.

When the voltage is less than 5V they can be neglected. However when I measure it, OUT is only 2. The diodes need, according to the datasheet, a minimum of 20 uA to operate. Sign up or log in Sign up using Google.

Add that to your 5Volts, and you have Tony EE rocketscientist 62k 2 21 Em Ka 48 7. Andy aka k 10 Then the curtain will rise. D2 and D3 cannot magically make 5 volts appear at the junction of R1 and R2 if the basic voltage at the point is less than 5 volt when D2 and D3 are not present.
