LM3886: pin mismatch using TI-TINA and LM3886 model

Jan Hofland98

Part Number: LM3886

Using TINA to try and model LM3886 behavior in a simple gain of 10 circuit. Get the ERC error TLD pin: INP does not match any pin of the macro component (LM3886). The + input connects to a 1K/10K resistor divider. Is there a model problem?

hello sir,

could you show us more detailed your model setup?

I chose the LM3886 from the Spice macros >other components.

It has the following connected components

1K between - input and ground.

10K between - input and output

1K from signal source to + input, 10K from + input to ground.

75K from mute to negative supply

10uF cap from mute to ground.

24V positive supply, -24V negative supply

8 ohm load from Vout to ground

I can provide a jpg showing the circuit and error message if I know how to attach it to this reply.

It is noted that the symbol associated with the Spice macro LM3886 does not match the subckt pin list of INP INN VCC VEE GND OUT MUTE

Hi,

Yes, I've tried but also failed. There should be something wrong in the TINA library for LM3886.

However, if you would like to run simulation for LM3886, please go to http://www.ti.com/product/LM3886/toolssoftware to download the TINA model.

This model can work well. Thanks!

Regards,

Hao
