Faulty LM358 SPICE model
I'm trying to find a working spice model for the ST LM358. The one on the site gives an output of -12KV for a small sine wave when powered from ± 12VAnd the "contact us" email doesn't work.

Wiring issue with BIG KEY button module on Arduino?
Has anyone used those BIG KEY button modules before? I’m trying to hook one up to an Arduino, but I’m not sure if I’m wiring it right since the signal seems stuck low. Do they normally need a pull-up resistor or should it just work out of the box?
STA540 BTL parallel
Dear technical teamI'm designing a triamped system with the STA540 , in fact it uses two STA540's per unit. I've divided the system in one STA amplifying stereo treble and mid, and other STA for bass amplifier, but given that bass channel is not ste...
