Part Number: LM4755 Hi,
I constructed a prototype using the schematic as shown on page 2 of datasheet (typical application).
The voltage supply was set to 22 V dc. I noticed that the output starts clipping at around 7.5 V (bottom of waveform). …
Hi, Deepak,
Thank you for your feedback on this. I have some other questions for this issue.
Have you tried with more units on this? I mean, have you replaced the LM4755 with other samples and do you have the same issue?
Could you try with a different…
Part Number: LM4755 Hi Luis,
How much max voltage can Mute Pin Handle?
I am not seeing anywhere, if we talk about TINA simulation with the Preferred values in the Datasheet as below i can see with R=12K and C=10uF i can see Mute voltage =Supply voltage…
Part Number: LM4755 Could you please tell me the operating temperature for the LM4755? It appears it's only available in one variant with part number LM4755TSX/NOPB. I see several locations where it's range is listed at -20 to 80 deg C, but on page 3…
Part Number: LM4755 Hi,
Currently i am facing issue with the calculating the current through IC
I have used LM4755 in my design
Speaker impedance is 45 ohm
Voltage across speaker is 5vrms
Vcc=16VDC.
How to calculate the Total current pass…
Hi, Deepak,
The dB units always depend of a reference.
In power units, there are dBW and dBm units to refer the gain relationship between a 1W or 1mW.
dBW means dB relative to 1 watt, so 0 dBW = 1 watt, -3 dBW = half watt. +3dBW = 2 watts etc. …
Part Number: LM4755 Other Parts Discussed in Thread: LM4911 I have been working with the TINA reference design for this and it seems that the models shows an ~70mS delay for start up or when the devices is muted, then unmuted.
Is this model behavior…
Part Number: LM4755 Please advise on what to do with the INA and OUTA pins of the LM4755 if they are unused.
Conditions:
INA=GND,OUTA=OPEN ,Result: IC heats up
INA=GND Via 0.1Uf,OUTA=OPEN (as per simulated circuit)- IC heats up
INA=OUTA…
Part Number: LM4755 Hi,
some time ago the LM4755TS was set to obsolete Status.
Now ist is again available under LM4755TSX/NOB.
We odered some samples for evaluation but they are branded with National Logo not TI.
Can you confirn that LM4755TSX…
