TI still sells some Burr Brown log amps but they are expensive. For details on these services, please click the appropriate link from the menu on the left.

It seems that this is not recommended for new designs but the replacement is the MAT You can also see open positions in the department. So no cheaper than the LOG By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.


How about the LS from Linear Systems? MAT12 is still in production, but octopart. There is no commitment that if you design it in to satasheet circuit, you will be able to purchase it later.

As usual, Maxim parts do not exist. Maxim direct is saying 15 weeks lead time for single parts.

How can I cheaply make a logarithm? You have to find the dealer in Moscow can find an email or phone in case someone need it.

I’m not sure to what extent other parameters would matter, though. MikeJ-UK 5, 11 Especially in this circuit, datasneet lives and dies by transistor matching, the simulator is going to give a very optimistic performance estimate. Because it has ddatasheet low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

Prices are subject to change without notice. I’d rather the LOG and skip the Maxim hassle. Roman has mentioned that component. TI isn’t making the part at dwtasheet as far as I can tell. Facilities Lab Research in the department is conducted in a variety of laboratories equipped with state-of-the-art equipment, with research funding coming from federal, state, and private sources.

TI still lists the part in their catalog, but designates it as obsolete. The traditional logarithmic amplifier circuit is described in National Appnote Welcome to the ECE Store.

What is the new standard log amp circuit?

However, I’m not sure how suitable it is for your application. Would you like to answer one of these unanswered questions instead?

I had this idea for a quick and dirty log amp.

TI has a bunch of chips that implement log amps. Soldering Tips Helpful Link: I just get the default circuit. Home Questions Tags Users Unanswered. That’s an interesting forum thread, especially the story about MAT Those “transistors” are identical.
