Part Number: LM4952 Tool/software: The LM4952 is used in the range of VDD from 11.7 V to 15.9 V, but when VDD is approximately less than 12 V, no sound may be output after power-on.
The shutdown pin is controlled externally with a voltage of 3.3 V, but…
Part Number: LM4952 Hi team,
In the datasheet for LM4952, only typical value is listed for volume control section. My customer has requested us to provide maximum/minimum spec for VOL_max and VOL_min.
Is it possible to provide spec information?
If not…
Part Number: LM4952 Hi team,
Could you please let me know how to estimate power supply current when RL=8Ohm (4W) speaker and VIN=12V?
The datasheet shows that for RL=4Ohm in Figure 35. But I cannot find what I want (RL=8Ohm).
Regards,
Itoh
Part Number: LM4952 Other Parts Discussed in Thread: LM4950 Hello Sir:
Can you recommend a pin to pin part for replacing LM4952?
Or can you recommend a class AB part and the total dimension is smaller than LM4952?
Please help to provide recommendations…
Part Number: LM4952 Hi team,
Customer has concern about click noise. They understand 1dB/step is minimum step. But they want to reduce click noise at external circuit. Could you give me advises to reduce click noise?

Part Number: LM4952 Hi Audio team,
My customer is considering to use LM4952 as 64ohms headphone amp driver. Do you have any data with 64ohms load with following condition? > 12Vdd, 10/20% THD+N
In addition, is it ok to use LM4952 as 64ohms headphone…
Part Number: LM4952 Hi Team,
I have a question about power supply bypassing.
LM4952 datasheet says 10uF tantalum bypass capacitor is needed for power supply bypassing. I think this is because of phase margin.
Question here is is it ok to use electrolytic…
Part Number: LM4952 Hi All,
I am currently using one channel, channel A (pins 2 and 4) on the LM4952TS chip.
My question is what do I do with the unused channel B pins. Do I short pin 8 (-VIN B) and pin 7 (VOUT B) to GND?
Look Forward to your reply.

Part Number: LM4952 Other Parts Discussed in Thread: TPA3125D2 Dear Sir
We need 8ohm/5W@12Viin single-end output stereo audio amp
May I know which TI solution can support
Molla,
I mean a resistor in parallel with Bypass cap to discharge it, it could be connected through a transistor to avoid the connection of the resistor when the device is operating.
The diode could also be a solution, I think this solution discharges…
