цитата:

не получилось(и не у меня одного) сделать рабочую модель от TI.

Затаривай! Режим тишины (Mute) подключается 7-й ногой на минус питания

* LM3886
* Version 1.0 :
* Free for Microcap

*****************************************************************************
* Notes:
* The LM3886 Macro Model represents the following parameters for
* split-supply operation (+/-28V):
* GBWP, input-referred voltage noise, the quiescent current,
* output swing, input offset voltage, input bias current, PSRR,
* CMRR, and the slew rate.
