Part Number: LM4880 Other Parts Discussed in Thread: NE5532 , TPA6139A2 , TPA6138A2 I'm trying to implement a pop-free circuit with the LM4880 that is connected to a 10 ohm headphone. I use the LM4880's shutdown pin to mute and unmute but I'm getting…
Part Number: LM4880 Other Parts Discussed in Thread: TPA6111A2 I'm working on a product which includes a headphone amplifier, using an LM4880M. I'm producing a low-frequency signal using a DAC, which feeds into the LM4880M. I'm seeing significant noise…
Part Number: LM4880 Looking at the LM4880 datasheet, it says that it is possible to connect the shutdown pin directly to a GPIO pin of an ucontroller respecting the voltage of the GPIO. My question is if it is not better to put a referencial resistor…
Other Parts Discussed in Thread: LM4880 I am working on updating a design due to the fact that the LM4882 is now obsolete. I have decided to change the amplifier to the LM4880 which is basically the same as the LM4882 with the exception that it is Dual…
Other Parts Discussed in Thread: LM4880 Dear All:
I can't find the LM4880 output impedance on the datasheet.
Do you know what its the LM4880 output impedace?
Regards.

Hello E2E,
I'd like to know the temperature dependence for harmonic distortion for following products.
- TPA6111A2 - TPA6110A2 - LM4880 - LM4881 - TPA0211…
Hi Yoshihiro,
These devices are quite old and it could be difficult to get the plots you are requesting. I would suggest you to use our Audio Selection Tool and take a look to our latest Headphone Amplifiers. Maybe LM4880

Hi Alexzuev,
Welcome to e2e.
Unfortunately there is not an exact replacement with the same functionality as LM4910 in SOIC package.
Some similar devices are TPA6110A2, TPA6111A2, LM4880, LM4881. Although these devices doesn't feature a bias output…
Other Parts Discussed in Thread: LM4880 I got the EVM for the TPA6132A and tested it on the bench last night. All I can say is "WOW". I am beyond impressed with this device. Running from a 7805 and a 9V battery, the rails were very clean. I tested it…
