TLC2272: TLC2272

Prodigy 50 points

Part Number: TLC2272
Other Parts Discussed in Thread: OPA657, TINA-TI

I designed a circuit(Trans impedance amplifier + Pre amp + LPF)

I use opa657, tlc2272.

but there is an error when i simulate with orcad pspice( i have license. it is not a lite version)

If i draw this circuit on Tina-Ti samely, it worked!

what happend? I want to adjust my circuit to work in pspice too.

In pspice, if i eliminate third stage(LPF) , it work successfully. but when i attach it again, it didn't work.

    Seung,

    The only thing I can think of is that the last stage you had drawn in the ORCAD is corrupted - try to re-enter it piece by piece (don't copy and paste).

    Tina-TI is a PSpice based simulator thus its macro-model netlist is identical to PSpice netlist used by any PSpice simulator including ORCAD.

    If the problem persist, please contact ORCAD for technical support since you claim the simulation does work in Tina-TI.
