TL082: TL082 open loop gain and 3dB frequency

MINKYUNG KIM

Part Number: TL082
Other Parts Discussed in Thread: LF347, LF353-N, LF347-N, TL084

Hi, there.

1. I'd like to ask you information of TL082 open-loop gain and 3dB frequency.

I couldn't find any related figure in the datasheet.

2. I also wonder how I can find the maximum capacitive load, when the data sheep doesn't provide Overshoot vs. Capacitive Load

Thank you in advance!

Hi, there.

I just resolved the issues that I asked on previous page.

3. My customer asked me the Input capacitance of TL082. It isn't provided on datasheet.

Thank you in advance for your prompt attention!

Hi Mikyung,

data is vavailable for the LF347 and LF351 which might be similar:

Hello Mikyung,

It is similar, but input capacitance for the TL082/TL084 is a little higher than the LF347-N or LF353-N (the -N matters here)

Cp = 5.5pF (non inverting pin to ground)

Cn = 7pF (inverting pin to ground)

Cd = 4pF (inverting to non-inverting pins)

For unity gain capacitance should be less than 200pF, better would be less than 100pF.

Kai, welcome back! I think it has been a while.
