Part Number: LM4673 Datasheets for various differential-input audio amps show single-ended inputs as having the input to IN- and with the IN+ AC-coupled to ground. Why is this, vs. having IN+ receive the input and IN- being grounded? I understand that…
Part Number: LM4673 Hi team,
Could you please provide the solution to solve the pop noise during power off? Thanks!
Please find the schematic and waveforms below. We've applied C19 with 1uF to solve the pop noise at power on.
Best regards, …
Part Number: LM4673 Hi Team, We have a customer situation regarding the bxl file of WSON-8 package downloaded in CAD/CAE symbols. You can see in the image below about the solder mask opening and stencil opening discrepancy.
The customer applied this…
Part Number: LM4673 I posted in another thread with a similar question, but I was never answered... https://e2e.ti.com/support/amplifiers/audio_amplifiers/f/6/t/536666
I'm seeing the same issue everyone has with this device. When the SHDN pin is tied…
I'm seeing a similar issue during power up with my design. I have SHDN tied directly to Vdd. Sometimes when I power on the device the amp starts and other times it doesn't. This is extremely frustrating behavior as NO WHERE IN THE DATASHEET is it mentioned…
Other Parts Discussed in Thread: LM4673 I am using LM4673, with this 8E speaker is uesd. When I am playing 1Khz sine wave audio file, in starting volume level is good but after 3 sec volume get decreased and it is constant upto end.
Other Parts Discussed in Thread: LM4673 Hi Ti team,
I am using LM4673 power amplifier.
This Power amplifier is getting damage.
In our voice processor as per DAC gain peak to peak voltage will vary. So I am taking here two different peak to peak…
Other Parts Discussed in Thread: LM4673 Hello,
We are using the LM4673, with 0.1uF capacitor and 76.8K resistor on each of the IN -/+ from several different speaker types while testing. The speakers are 6 and 8 Ohms. We are looking for a solution to…

I am using LM4673 for my design with following use case:
Module can support only RL= 32 Ohm with 90mw so to amplify this I am using power amplifer…
Other Parts Discussed in Thread: LM4673 Hi
I am using LM4673 class D audio Amplifier and as per datasheet it is recommended that if we will use 4ohm speaker then power supply should be 5V but it is not working. I tried with 3.3V also, in short 4 ohm…
