Part Number: LM8261 Hello,
Our customer use the LM8261.
The condition of the customer using as follows.
Voltage follower circuit
V+=12V , VIN=VOUT=10V
Load: 60uF capaitor
Current limit resistor: 5 ohm
When the power up and power down, it occur inrush…
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…
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 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…
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…
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+.
Regards,
Hooman
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…
