Part Number: LM4890 Tool/software: Dear TI experts,
My customer considers LM4890 for their new project.
And they have to turn on and turn off using shutdown pin, about more than 500 times a day.
Does It affect to the lifetime of LM4890? My customer…
Part Number: LM4819 Hello, My customer is looking for P2P replacement speaker amp of KEC KIA6419F (I attach the datasheet). Can KIA6419F be replaced by LM4819? Does TI have any other better candidates? KIA6419F.pdf Best regards, K.Hirano
Hi Ivan,
Thank you for your reply. The device is used for Buzzer amp.
If there are a pin-compatible and cost effective device with TINA-model, please let me know.

Part Number: LM4819 Hi
My customer have the pop noise issue when power down timing.
Output waveforms and schematics are below,
The condition2 is little bit improved the pop noise than conditon1. However. customer have to decrease the pop noise more…
Part Number: LM4819 Hello,
Our customer use the LM4819, have some questions about failure mode.
If the Vo1 and Vo2 pin short to GND, I think the LM4819 is damaged.
In that case, which damage mode occur short or open?
Does it occur fire or smoke…

Hello Chetan,
Welcome to E2E, thanks for your interest in our products.
You shouldn't have any problem using a digipot in feedback. As the datasheet mention, Cf is not required when the amplifier's gain is less than 10.
