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 the…
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
Alex

Part Number: LM4871 Hello, my client applied for a 50pcs sample and found that there was no output of 4pcs when the application was designed.
The following is a schematic diagram of the customer's design.
The design needs to push the 8Ω 2W speaker…
Part Number: LM4871 Hi:
The product I designed USES LM4871, and the following problems occur, please help guide,thank you.
The test phenomenon is as follows
1.When SHUTDN_PA is low, the analog ground and digital ground are connected together. LM4871 device…
Part Number: LM4871 Other Parts Discussed in Thread: TLV320DAC3120 , TLV320DAC3101 Hi all. I have an application using a LM4871 amplifier driving a small speaker. I need to add a headphone output to the circuit. May I do this with the LM4871? If so, is…
Part Number: LM4871 Hello,
I am using an LM4871 audio amplifier for my design. I don't know that how much power this will consume. For design PCB traces power consumption of LM4871 is required. Please tell me about total power consumption of LM4871.

Part Number: LM4871 Hi Sirs,
Sorry to bother you.
Could we connect LM4871 PAD to GND? (As below red circle)
Because it's should be better to connect ground if we need heat for a large area, but spec does not indicate whether the PAD should be grounded…
Part Number: LM4871 Other Parts Discussed in Thread: TPA6211A1 ,
Hi,
When I switch on the amplifier from Shutdown to ON mode by switching the SHUTDOWN pin from high to low, there is a loud pop sound at the speaker.
From the waveform at Vo1 (pin5), there…
Part Number: LM4871 Hello team,
My customer got a 3.4MHz 0.9Vp-p sinusoid waveform from pin8 to GND even no audio input, we can still see this high-frequency signal with audio input.
Could you help advise how to solve this issue?
