Part Number: LM4674 Hi Team,
I'd like to know the Junction-to-case thermal resistance of the LM4674. Please help provide this information to me.
Thanks!

Part Number: LM4674 Hi everyone,
I am going to expose my problem. We have had some issues about LM4674 Audio Power Amplifier. The schematic circuit implemented is shown below. This circuit is used for separating both, L and R audio channels on a 32 ohms…
Part Number: LM4674 Other Parts Discussed in Thread: TPA2012D2 , Hi Team,
In the datasheet, there is a short description about output short protection but details are not included.
I'd like to know about the mechanism of it. Does it monitor the current…
Part Number: LM4674 For /SDR and /SDL the datasheet claims "The LM4674 shutdown inputs have internal pulldown resistors" but never states what the value of those resistors are. What are the values? I'm configuring a system and I want to make…
Part Number: LM4674 Hi Sirs,
Sorry to bother you.
We are finished LM4674 schematic as below
LM4674.output.pdf
Could you help double confirm?
Any suggest are welcome.
Thanks!!
Other Parts Discussed in Thread: LM4674 Hi,
It's indicated on a datasheet as follows about the Shutdown voltage of LM4674.
<Datasheet P.5> Shutdown Voltage Input High : VSDIH=1.4V(min) Shutdown Voltage Input Low : VSDIL=0.4V(max) (VDD = 3.6V…
Other Parts Discussed in Thread: LM4674 Hi
I am asked about the degree of input resistance distribution of LM4674 datasheet page 6 from our customer. They ask the temperature dependency and distribution of lots too.
Best regards, Akio Ito
Other Parts Discussed in Thread: LM4674 Hi Team,
Advantech met EMI failure issue when using LM4674, they are doing filterless config, didn't mention how long is from their output to speaker.
I suggest to add LC filter at amplifier output.
Customer…
