I am trying to select an op-amp for an audio design with ADC's and DAC's. The LME49721 is one of the candidates, but I would like to be able to simulate it in TINA TI.

    Jens,

    The Spice models available for many SVA (National) parts are compatible with Tina, unfortunately the LME49721 does not currently have a Spice model available. We're working hard to develop models for our entire portfolio and we will update this thread when one is available. However if you would like to simulate the performance of audio operational amplifiers having a TINA model may I suggest

    Sound Plus line

    FET input: OPA1652

    Bi polar input: OPA1602, OPA1612, OPA1662

    Best Regards,

    I just discovered that a Spice model is now available for the LME49721.

    However, I have not been able to create a Macro in Tina TI from the .lib file, because I get an error message "Missing syntax element. Line:#106. X_U_Vn11         IN+_CMRR N5633970 vnoise PARAMS: ".
