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).
Bias 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 Hello Sir,
I have prepared Prototype for the LM4755 as attached below circuit.
Input conditions:
VDD=22VDC
INPUT SIGNAL:200mV (1KHZ).
Output yet not connected.
Here, problem is that
IC LM4755 is getting heat up when we powered up…

Part Number: LM4755 I am designing circuit with the Reference of LM4755
i dont know the function of Mute Pin
What hapen if i keep that is open?
Do we need transistor drive circuit to Give 5v as per the reference diagram

Deepak
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 through LM4755…
Part Number: LM4755 I am designing one audio amplifier with using of LM4755.
I want to achieve 84db output BY UL Standard.
I have pre-selected speaker impedance is 8R
Max power handling capacity of speaker is 8 watts.
I could not able to figure out how…
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 indicative…
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=GND= IC does…
Part Number: LM4755 Other Parts Discussed in Thread: LM1877 Hi Team,
We found there is output noise from LM4755 when connected to external pre-amp and larger speaker through RCA cable.
Usually LM4755 is connected to Speaker (~2W). My customer is designing…
