  • LM48511: Layout example

    Resolved
    Part Number: LM48511 Hi, Is there a better image of the recommended layout for this amplifier? The one in the datasheet is not clear and with the multiple grounds and caps it would be good to have some guidance. Thank you.

  • LM48511: Amplifiers 1.3W to 5W

    Part Number: LM48511 Hi, I have a CPU board which can deliver 1.3W watt into 8Ohm Speaker as differential. (1.3W is not enough for my system) I have 4Ohm 5Watt speaker at the other hand. Could you help me which amplifier should i use to drive this speaker…

  • LM48511: I'm trying to use the LM48511.

    TI Thinks Resolved
    Part Number: LM48511 I am trying to use the LM48511. I want to connect 8 ohm speakers and maximize the gain. Looking at the datasheet, I don't know how to tune the gain. Can you please provide documentation and instructions on how to set the gain…

  • RE: LM48511: Random pulses in Vboost making popping noise in the speaker.

    I just noticed this from the data sheet - maybe the boost regulator is running in discontinuous mode? The LM48511 will limit its switch current based on peak current. With IP fixed, increasing L will increase the maximum amount of power available to the…

  • LM48511: Damaged after a day long of use

    Part Number: LM48511 To Whom This May Concern: I am evaluating the LM48511 audio amplifier in a prototype, and initially, it seems to be working well. I've since run it all day (2K sine wave input) generated from an audio codec (NXP SGTL5000), and some…

  • LM48511: PV1 is reading higher than is expected

    Part Number: LM48511 According to our calculations based on formulas in the datasheet, we should see an output on PV1 (TP154) of 7.97V. All of the boards we have checked are reading 8.5 to 8.7V. Can we get a schematic review and/or any insight into what…

  • LM48511: Grounding when using external boost power supply

    TI Thinks Resolved
    Part Number: LM48511 I am planning on using an external power supply for system architectural reasons. In review of the data sheet, I see that LSGND is the H-bridge ground and REGGND is the ground for the boost supply. What is the recommended scheme for…
