Part Number: LM4951A Hello team,
My customer is evaluating the LM4951A with setting Ri=100kΩ(95.0kΩ~105.0kΩ) and Rf=510kΩ(484.5kΩ~535.5kΩ).
Base on the above setting, the gain range is 9.2~11.3(typ: 10.2). But the result they got is 8.9(Vinp-p=0.080V…
Part Number: LM4951A Hello team,
My customer is evaluating LM4951A now.
Should the lengths of the Vd+/Vd- to Out+/Out- wires need to be equal?
In the case of our EVM, these are equal.
Best regards,
Shotaro
Part Number: LM4951A Hi,
I'm working with customer on a protection circuit application on LM4951A Vin whereby eFuse added upfront on supply end to ensure protection circuit kicks in to limit Vin to LM4951A. However I noticed that I'm experiencing bad…
Part Number: LM4951A Hi,
What reliability testing has been done on this part? And what was the supply voltage used for reliability testing? The datasheet says the supply voltage range goes up to 9V but the graphs below are tested at 7.5V. Any and…
Part Number: LM4951A Hi team,
My customer faced pop noise issue when turn on the shut down.
Please see the schematic and waveform below.
Could you give your advice how to prevent the pop noise?

Part Number: LM4951A Hi,
Just a quick question on the function of the Cchrg pin. It looks like this is used to quickly charge the input cap. Could this pin be left floating? What affect would this have on operation?

Part Number: LM4951A Hi,
1. What does it mean by internally limited on power dissipation field under absolute maximum rating?
2. If Vdd is 8.4V, speaker load = 16ohm,
Based on the equation 2 in datasheet, Pd = 4*(8.4^2)/2*pi*16 = 0.89W.
Then Ta…
