Part Number: LM49251 Dear Sir,
We are estimating the playback time for a battery operating product.
The product will use speaker in LS (stereo input, aLC on) mode 2. If the total power consumption (excluding power use for sound producing) is typically…

Part Number: LM49251 Hi Team,
May I know the input range of LM49251? Usually amplifier will introduce the input dynamic range, 1Vrms or 0.7Vrms mainly, but I can't find this data at LM49251 datasheet, could you help to provide? thanks a lot!
Best…
Part Number: LM49251 Hi All
I'm having problems communicating with my LM49251. The data sheet seems to have some conflicting information and not fully detailed.
I would like to know the correct data sequence for I2C communication. I am currently…
Part Number: LM49251 Hello all,
For the LM49251 device, Reference Datasheet (page 3)
Figure 2. Typical Audio Amplifier Application Circuit.
Are INL1/INL2, INR1/INR2 and volume independently controlled?
Hi Paul,
Thanks for the feedback.
The TLV320DAC devices I mentioned are still options for this, these have analog inputs in parallel to the DAC, and both connected to Speaker and Headphone output. Similar option would be TAS2505.
Some other options, although…

Hi Ivan & thanks a lot for the answer.
So I can get 2 different audio sources in parallel on 2 separated outputs. Cool !
Does this apply to LM49251 too ?
Kind Regards
Nicolas
