I don’t understand what you mean by resistive voltage divider – could ddatasheet please explain? Em Ka, D2 and D3 ‘start working’ when the voltage is higher to 5V in.

The diodes need, according to the datasheet, a minimum of 20 uA to operate. The circuit operates as a resistive voltage divider. That adds up to a minimum of 0. Sign lk385z or log in Sign up using Google. I changed R2 and R3 to 47k and 22k and all works fine!

Enric Blanco 4, 5 11 Andy aka k 10 D2 and D3 cannot magically make 5 volts appear at the junction of Datasheef and R2 if the basic voltage at the point is less than 5 volt when D2 and D3 are not present. Could someone explain me please what am I missing? To achieve the desired result descending resistance R1.

AltAir 2 And it is so, if R2 and R3 are not present in the circuit. Select a lower datasheett for R1. Post as a guest Name.

If you don’t feed them with enough current and voltage they are just resistors. As if they are not.

Add that to your 5Volts, and you have This, of course, ignores your bias current through your Daatsheet 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.

Then the curtain will rise. Besides, from what I understand datashdet across anode of D1 and cathode of D2 should be always 5V, right? Em Ka 48 7. You must select a value well below this.

When the voltage is less than 5V they can be neglected. You need to drop the 10K to a lower value, or use two datashewt, 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.

Email Required, but never shown. I’m doing a simple circuit using LM However when I measure it, OUT is only 2. Tony EE rocketscientist 62k 2 21
