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 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,

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…
Part Number: LM4861 Other Parts Discussed in Thread: LM4876 Hi Experts,
We need your advise and confirmation whether both IC (LM4861M/NOPB & LM4876M/NOPB) can be operated in closed/open loop gain? Our customer is driving 1W,8ohm speaker using LM4861M…
