Part Number: LM4876 Hi,
My customer is in trouble by pop noise when shutdown(ON→OFF).
What should they change external components from following circuit to improve pop noise?
Best Regards,

Part Number: LM4876 Does the LM4876 work with polarized speakers? I want to use this amp to drive CUI's GC0401S speaker.
My understanding is the differential outputs are not polarized; either signal can go to either terminal. The GC0401S has "+" and…
Part Number: LM4876 Other Parts Discussed in Thread: TL971 What is the best way to control volume with a 1W speaker?
My thought is to us a digital pot as the feedback resistor in figure 1 of the LM4876's datasheet. Is this a terrible idea?

How is gain defined for a differential op amp?
Using the LM4876 and the datasheet, I made the circuit in figure 1 with Rf=42K and Ri = 20K. According to equation 1, my gain should be ~4.2. I am actually only seeing a gain of ~2.1.…
Hi Gerald,
The internal bias and gain resistors are not the same across these devices, but the overall functionality is still the same. Customer can replace LM4861 with LM4876, just take into consideration that shutdown logic is inverted:
LM4861 will…
