OPA1612: PSpice model for Altium
TI Thinks Resolved
Part Number:
OPA1612
Hi Team, We have received a request from a customer for a simulation file of
OPA1612
for Altium Designer. I have shared the PSpice model from this link https://www.ti.com/lit/zip/sbom396 . It seems Altium can't recognize the...

RE: OPA1612: OPA1612 distortion
Hi Paul, Thank you for your clarification. I understand your schematic is in as below. As you can see in this simulation result, we can see the gain peaking in frequency - gain curve without additional load. If you could not see any gain peaking...

RE: THS4130: Dimension for thermal pad
Your images did not come through, use the little paperclip in the ribbon to insert files. Also, the
OPA1612
is the same part and it shows pretty good information for this starting on page 30 of the datasheet,

RE: OPA1656: Datasheet Fig.7, THD+N not rising with frequencY (load=2k and Vout= 3V(rms) )
Hi Frank, I have not found any exact characterization data you expected so far. While, I suppose the flatness of THD+N vs. frequency in 10 - 20kHz might not change in 8Vrms output condition for
OPA1612
/56, considering with its output impedance curve...

RE: OPA388: Low flicker noise operational amplifiers / Is the OPA388 completely 1/f noise free?
Hi Michael, Thank you very much for your help, It appears that there are several zero drift operational amplifiers from TI which may meet the design requirements. There are lots of options there. What do you mean with "a sampling front end...

RE: REF3425: output capacitor value
Hi Marcoo, I can try OPA211 or
OPA1612
with 100uf capacitive load. What is the buffer's BW requirement? Please let us know. Best, Raymond
