Part Number: LM8261 Other Parts Discussed in Thread: OPA890 , OPA690 Hello,
I currently use LM8261 in an improved Howland current pump design. Current pump is supplied by +/-5V sources and is designed to output 100kHz sinusoidal 4mA pk-pk current. It…
Part Number: LM8261 Hello,
Our customer use the LM8261 with heavy Cap load as 69uF.
A large current flows in output line. So, it may be over temperature at junction of the device.
The customer have a question. How about the thetaJC?
It is 110 degree at…
Hi Alex,
The LM7321 does have the unique unlimited capacitive load architecture that allows for better stability while driving a capacitive load. I thought it would be challenging to replace a quad channel device, like the TLV2374, with a single channel…
Part Number: LM8261 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi,
The LM8261 SPICE model source E1 is referenced to ground with only 100kohms as series resistance. That makes the simulation model inaccurate with high…
Part Number: LM8261 I am using this op-amp as a voltage follower (i.e. unity gain). The input comes from a signal generator, generating a 1kHz, 1V amplitude triangle wave, with a +6V offset. The op-amp has the output connected directly to the inverting…
Hello Jagdish,
The stepped-gain amplifier is what avoids the overloads - and it's final gain (35dB) is higher than your external amp. You would be better off using that - as intended.
Are you changing R16 or R17, or both?
Changing either of these…
Other Parts Discussed in Thread: LM8261 , OPA140 The time point when the abnormality was found: during verification on the machine
Abnormal information: The test result shows that the signal of the OP amplifier is abnormal. Connect the signal generator…
Other Parts Discussed in Thread: LM8261 I've got an LM8261 that's driving a high resistance, low capacitive load (1megohm+, less than a few nF). Essentially, the output current draw is negligible. Supply rail is 18v, and the LM8261 is the only…
I live and work in Germany, we order normally from Germany. i think we have to order it from USA i think. People have used LM8261? does it works good like LM7321? We have electronics with LM7321 which works very good but I do not know how it will be with…
Hi George,
FYI: The LM8261 datasheet typo (with regard to its absolute maximum input / output voltage rating) has now been corrected to show 0.8V beyond both V- and V+.
