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…

Part Number: LM4871 Hi
If LM4871M device is connected to audio transformer, can I still use formula 2 from datasheet, page 10 to calculate power dissipation?
What transformer value I need to use for RL (Impedance or DC resistance)?
Best Regards…
Part Number: LM4871 Hi Team,
In order to avoid pop noise at startup, I pulled Shutdown pin to high but found that output was still functioning, meaning that the Shutdown function was not active.
What's the actual function of the Shutdown pin?
If…
