Part Number: BUF634A Other Parts Discussed in Thread: LMH6321 , , BUF634 , TINA-TI Hello,
We have compared the performance of two IC buffers: BUF634A and LMH6321 to drive a large capacitive load (e.g., 1nF) using a very simple circuit. Simulation results…

Hi TI Technical Support Team,
I am aiming to design a circuit that will be used to test for example battery. The circuit will apply +/-5V and also be capable of delivering +…
Part Number: LMH6881 Other Parts Discussed in Thread: LMH6321 , PSPICE-FOR-TI , TINA-TI hi TI
Using the lmh6881 simulation model downloaded from the official website, the peripheral input circuit is modified, but the simulated magnification is less…
Hi Ahmet,
I put together a circuit and see if it meets your requirements. I am using BUF634 instead of LMH6321. Either buffers should work. The phase margin of the circuit is approx. 68 degree with BW is approx. 3.0 MHz.
If you want to have LMH6321…
Hello Jonathan,
The LMH6321 may be a better option here as it is more capable in driving capacitive loads. You didn't mention which supplies were being used, be sure to confirm that you aren't exceeding your output swing conditions. Note that if an…
I see what you are saying, that is very odd to not provide a small reel of the SO-8 powerpad, certainly the number of build flows and inventory issues come into play - I think this is intended as an upgrade path for the older OPA634 where those smaller…
Part Number: BUF634 Other Parts Discussed in Thread: , LMH6321
Kind of parsing through some options for an imbedded power boost design where the old BUF634 and improved BUF634A show up regularly.
I had a comparison file set up anyway, and was astonished…
Hi Ke,
Here is the connection diagram found on the first page of the datasheet. Usually the dip in the package indicates where pin 1 is.
Also for open loop applications we have an EVM user's guide that can help you understand how to set the LMH6321…
Hi Fred,
I forgot to ask what types of waveform is 22uA signal as in put. Anyway, I put together something that might work for your application. Using LMC6001 op amp, I added BUF634 buffer at its output. BUF634 is rated up to 250mA. It should be good…
