CaptnYellowShirt on May 13, A stabilizing heater is incorporated with the active Zener on a monolithic substrate which nearly eliminates changes in voltage with temperature.

There are some differences to mention: May 13, An R2 of 6.

BOM costs thus far: I was going to ask why they don’t have it on the other circuits link the one at the very top “10V Buffered Reference” but your last sentence answered that for me thanks!

Screen Shot at 9. Some black magick trick. This means I can immerse the entire circuit in an oil bath and not have to crack it open while dayasheet to tweak a pot, etc. If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI. The Sample button will be displayed if a model is available for web samples.

Andy aka k 10 X-axis is heater voltage left Y-axis is 2: This struck me as being interesting, because this greatly reduces the parts count, and also because the only pins ,m399 need to touch a voltage regulator are the op amp supply pins.


Test setup is the same as previous post. Screen Shot at 8.

I came across an interesting current source in the LM datasheet: Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read datasyeet updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

We do take orders for items that are not in stock, so delivery may be scheduled at a future date. A bit like when you don’t supply enough voltage to a motor – if you give the rotor a bit of a spin you can get the motor to begin rotations i.

Andreas on May 11,eatasheet We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. I’ve had a raw LM hanging on magnet wire from a HP power supply for about a month now — just swinging in the air over my bench.

Price Rohs Orders from Analog Devices.

LM based 10 V reference – Page 8

It looks like it forms a voltage divider with the k resistor, but I cannot figure out why they have that in there? My first attempts were a traditional op-amp with current sense resistor on the low side. Additionally, it will keep that current fairly constant because the 10 volt output will be constant. The package for this IC i. I thought this arrangement might dayasheet interesting for use with driving an LM By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

That’s partly because the LM is represented by an 8. Thanks Andreas Quote from: ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.

Pin Count Pin Count is lm939 number of pins, balls, or pads on the device. It’s basically a zener diode and with not enough current it won’t regulate very well.

I’ve really enjoyed these volt-nut threads and though I’m a newb, I’ve started down my own path of designing an LM reference. Transit times from these sites may vary. Tony EE rocketscientist 62k 2 21 Once an order has been placed, Analog Devices, Inc.

The model has been scheduled for obsolescence, but may still be purchased for a limited time. A 10V buffered reference application is shown below. The LM requires that its operating current is between 0.

Andreas on May 24, Uh oh, 10 minutes at the breadboard and I’m officially addicted to volt-nutting.

Seems to work quite well. The various ranges specified are as follows:.

One could top it off with a Petri dish? Also, please note the warehouse location for the product ordered.
