Hi everyone,

I am working on a LTSPICE model for TL062 

I think maybe you can help me :)

This is the schematic diagram is the datasheet :

and this is my spice model

To test if my amplifier is working i am trying the basic utilisation for OpAmp :

So I connected Vcc+-, Vout with - and put an input voltage

This is my result :

I don't understand why it gives me this

    Hi,

    why ..? model from Ti not good ? https://www.ti.com/lit/zip/sloj066

    You Q19 is not , whats in the basic circuit . (double collector pnp)

    Try connect its collector to J1 (NOT the basis ). Maybe works - check currents.

    Or use 2x pnp in parallel, except collectors - to come close to a double collector pnp (only on chip possible).

    It is not good because it does not have the same caracteristics

    It tried with a 2x pnp but it is worse ...
