Lt3092, if the input voltage is fixed and the input voltage is greater than 40V, the output current can be adjusted. How to build the circuit? Thank you very much.

Hi, 

Just wanted to know if the LT3092 Current Source IC is available in 8 pin through-hole package because I only see Surface Mount options on websites. 

Please could you suggest alternatives with through-hole type pins that can be used on a breadboard…

Hi, 

Please can you tell me how to use the 8 pin LT3092?

There are 3 input pins, 2 output pins and 1 SET pin. How would I connect these inorder to build a current source using two additional resistors (like shown on page 1 of datasheet)?

Would I have to…

想问一下，输入电压固定70V，然后输出电流可调0.5ma~100ma     电路怎么搭建？

Does this circuit work?  I don't know why the circuit I have drawn is not working.  I want to keep the current between 0-2 K load constant with DAC at the desired value between 0.5-20 mA.  I want to keep the current between 0-2 K load constant with DAC…

A customer asks about the LT3092, "do you have an example of the schematic diagram and the PCB track for the SET pin guard ring, as recommended in the datasheet." 

I will answer the post myself.

Hi, all,

in the CN-0540 there is a note that there was done an LT spice simulation of the constant current source (based on LT3092) to optimize its noise performance (see Constant current source section, p.3). Is it possible to get more details about this…

I need to build a current source to calibrate a product in manufacturing.  I would like to calibrate the current source annually and know what it's drift might be like over the year.  I see no such data in the datasheet.

Mike.
