This, of course, ignores your bias current through your LM Tony EE rocketscientist 62k 2 21 Sign up using Email and Password.

However when I measure it, OUT is only 2. To achieve the desired result descending resistance R1. AltAir 2 Could someone explain me please what am I missing? If you don’t feed them with enough current and voltage they are just resistors.

Email Required, but never shown. You must select a value well below this. 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.


Post as a guest Name. As if they are not. I changed R2 and R3 to 47k and 22k and all works fine!

Just think about it a while and calculate what the voltage at that junction is with D2 and D3 removed. However, at 4V voltage drop, the 10k resistor can only provide 0. Home Questions Tags Users Unanswered.

The diodes need, according to the datasheet, a minimum of 20 uA to operate. Dtaasheet the voltage is less than 5V they can be neglected. Sign up using Facebook. You need to drop the 10K to a lower value, or use two batteries, but make sure datashewt don’t exceed the maximum bias currents for your references. Em Ka 48 7.

That adds up to a minimum of 0. Em Ka, D2 and D3 ‘start working’ when the voltage is higher to 5V in.

I don’t understand what you mean by resistive voltage divider – could you please explain? Then the curtain will rise. Om385z it is so, if R2 and R3 are not present in the circuit. Enric Blanco 4, 5 11 I’m doing a simple circuit using LM By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

You can’t do this with one 9V battery. 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. Add that to your 5Volts, and you have Select a lower value for R1.
