  • LM4880: Can I connect the shutdown pin directly to a ucontroler or you be better to put a resistor in parallel with the shutdown pin?

    Resolved
    Part Number: LM4880 Looking at the LM4880 datasheet, it says that it is possible to connect the shutdown pin directly to a GPIO pin of an ucontroller respecting the voltage of the GPIO. My question is if it is not better to put a referencial resistor…

  • RE: About output power vs supply voltage for high power HP AMP

    Hi Yoshihiro, These devices are quite old and it could be difficult to get the plots you are requesting. I would suggest you to use our Audio Selection Tool and take a look to our latest Headphone Amplifiers. Maybe LM4880 Regards, -Diego Meléndez…

  • TPA6132A - WOW!

    Other Parts Discussed in Thread: LM4880 I got the EVM for the TPA6132A and tested it on the bench last night. All I can say is "WOW". I am beyond impressed with this device. Running from a 7805 and a 9V battery, the rails were very clean. I tested it with…
