LM Datasheet(PDF) – National Semiconductor (TI)

TI has a bunch of chips that implement log amps. Chris Johnson 7 This circuit looks to be a log amplifier using two op-amps, two transistors, a few passives and a current source. Thank you for datazheet interest in this question. I don’t know what the definitive chip is datasheef there are many chips that implement the whole circuit. Search the directory for faculty or staff members.

That would more-or-less be an interpolation between 3dB values.

The ECE Store provides many services to electrical and computer engineering students in order to create a safe environment in which students have access to the equipment and parts they need. How about the LS from Linear Systems? There is no commitment that if you design it in to your circuit, you will be able to dtaasheet it later.


The chip has almost the same name: TI isn’t making the part at all as far as I can tell.

So Maxim doesn’t have any either. To see a list of open positions, click here.

What is the new standard log amp circuit? Especially in this circuit, which lives and dies by transistor matching, the simulator is going to give a very optimistic performance estimate.

You have to find the dealer in Moscow can find an email or phone in case someone need it. Maxim direct is saying 15 weeks lead time for single parts.

That’s an interesting forum thread, especially the story about MAT For details on these services, please click the appropriate link from the menu on the left. Roman has mentioned that component.

Octopart is not comprehensive. Soldering Tips Helpful Link: Engineering Program is accredited by: TI still sells some Burr Brown log amps but they are expensive. Intersil makes a number of transistor arrays some are certainly single die and well matched. The traditional logarithmic amplifier circuit is described in National Appnote Our People Search the directory for faculty or staff members.


Welcome to the ECE Store

It seems that this is not recommended for new designs but the replacement is the MAT I’d rather the LOG and skip the Maxim hassle.

MikeJ-UK 5, 11 You can also see open positions in the department. Open Positions Datashfet see a list of open positions, click here. I can use LM array, but the specs are far worse. I tried adjusting the Hfe of the transistors and unless it was something like it kept a very clean log output.
