Part Number: TLV2314

hi support team.

pls help to confirm below spec for TLV2314. 

Application: GATE 10, input 200KHZ

1: our application need GBW is 2M, SR is 1.9V/S.   TLV2314 GBW is 3M,  SR is 1.5V/s.  it is can meet our application needs? thanks.

    Hello User,

    Even in the sample waveform, the output is a little smaller than expected and is adding distortion  (mismatches between input and output). The output peak to peak is about 7.5 times the input, but the programmed gain is 10. Some of the input detail is lost. Most do not realize that the input difference signal |pin3-pin2| needs to be greater than 100 mV to get the full slew rate of an op amp. This much "virtual ground" error generally causes some distortion. This is why audio amplifiers have far more gain-bandwidth and slew rate that would seem to be required. 

    Slew rate can vary across temperature, sample to sample, and lot to lot. How much more distortion can the application tolerate?

    I suggest using an amplifier with more bandwidth and slew rate.
