Part Number: LM4871 Other Parts Discussed in Thread: TPS61023 , Tool/software: Hello,
I am using 8 ohm speaker. connected output f DC DC converter TPS61023 to power LM4871. The boost converter converts 2.8V to 5V for LM4871. When I turned ON the volume…
Part Number: LM4871 Tool/software: I built up the circuit of LM4871M just as typical circuit shown, but the output of LM4871M would always be 5V. How could I solve it?
Part Number: LM4871 Tool/software: Hello, I have a question about the LM4871MMX/NOPB circuit.
The circuit is configured as shown in the attached image.
The problem is that Pop Up noise occurs when power is supplied.
In order to solve the Pop Up…
Part Number: LM4871 Hello,
My customer is asking about output protection on LM4871.
Does it have output short protection?
Or can it use the thermal shutdown protection instead of output short protection?

Part Number: LM4871 Hi,
we were modeling the basic configuration for the LM4871 both in PSpice for TI and LTSpice as shown in the part's data sheet (input signal to the inverting input of the amplifier). However, the simulation results do not match…
Part Number: LM4871 Hi Experts ,
Good Day ,
Can you please check and confirm below image which is having the wire bonding changes and Bottom markings are consistent with TI requirements ? . Both the date codes were belongs to Malaysia.
Please…
Part Number: LM4871 Other Parts Discussed in Thread: TPA6211A1 Dear experts,
My customer use the LM4871MX to drive a speaker, and test the speaker will have a POP sound at the moment of playback.
Testing conditions:
1. There is a POP sound during…
Part Number: LM4871 Other Parts Discussed in Thread: TPA6211A1 Dear TI team,
I need to know the amplifier's minimum and maximum input impedances because I plan to work on an LM4871 audio amplifier.
The schematic and DC resistance of the audio transformer…
Part Number: LM4871 Dear team,
I am planning to use LM4871MX for my design. I am planning to operate the device at 3.3V and device is expected to drive at 8ohms loads.
How much current should be supplied at 3.3v rails for proper operation.
Part Number: LM4871 Hello,
I cannot find the Absolute Max Ratings of LM4871's Vo1/Vo2 in the data sheet, however, how does the LM4871 behave if a voltage is externally applied to these pins when a supply to the LM4871 is turned off? Could it damage…
