Part Number: LM4871 Hello,
I'm wondering what kind of impact could be expected on two LM4871s and a speaker when outputs of the two LM4871s are temporarily connected together.
An LM4871 is used on a card in a redundancy system. When the card is being…

Part Number: LM4871 I am trying to run a simulation of a design that uses the LM4871, in the TI version of pspice. However, I get this error:
ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U1.XU11.EVCM. You may break the loop by…
Part Number: LM4871 Hi team,
When using LM4871 according to datasheet recommend, as below, R30=20kohm, R1=20kohm, the voice volume is not louder. If i want to increase the volume, could i increase the amplify gain, like R30=20k, R1=100k?
Would this damage…
Hello Ivan, Hello Justin,
sorry for the late response. You can find the analyze attached with some more information. Here the quick answer: 1. I checked our design and figured out that the main noise is produced by the two capacitors C26 and C27 (see our…
