Part Number: LM4991 Tool/software: Hi Ti,
Is there any problem with the following usage of LM4991?
Supply voltage: 5V
Maximum input signal amplitude: 5Vpp
Maximum output signal amplitude: 6Vpp (Av=1.2)
Best regards,
Part Number: LM4991 Tool/software: Hi Ti,
I am planning to use a digital potentiometer for the feedback resistor (RF) of the LM4991.
I am thinking of using this to control the gain, but is this a problem?
Best regards,

Hi,
My customer would like to use LM4991 at 25kHz.
However the characteristics(frequency vs Gain, THD+N) shown on the datasheet is below 20kHz as following.
(We're understanding that it is valid because LM4991 is audio amp…
Part Number: LM4991 Hi,
we have an issue with the LM4991. In our design the startup time is very important. We want to switch off the amp via the shutdown-pin between audio signals. 90 ms after we pull the shutdown to GND (to activate audio) the audio…
Hi, Nanokawa-san,
Thank you for your cooperation. We have obtained a reply from our customers. Our customers understood that LM4991 will be easy to get into thermal shutdown mode by using RL=4ohm, said that when they adopt a new set, they would like…
Hi Roberto,
I split your post into a new thread since this is no longer related to LM4991.
I can take a look at the messages you've got, but it seems you tried this in LTSpice, are you having the same results on PSpice?
Best regards, -Ivan Salazar…
Part Number: LM4871 Other Parts Discussed in Thread: TPA6211A1 , LM4991 , TPA2011D1 Hi team,
Our customer is looking for alternative for ADI SSM2211SZ. I've found that LM4871 is TI alternative by using BOM & cross reference tool.
Could you kindly…
