Frequently Asked Questions
What channel separation does LM4838MTE/NOPB provide between its 2 audio channels?
LM4838MTE/NOPB achieves 65 dB of channel separation between its 2 stereo output channels. A 65 dB separation value ensures that crosstalk between left and right audio channels is minimized to inaudible levels in consumer audio applications such as televisions, multimedia monitors, and portable speaker systems.
How does the integrated volume control in LM4838MTE/NOPB simplify a stereo amplifier PCB design?
The built-in volume control circuit in LM4838MTE/NOPB removes the need for external mechanical potentiometers or separate digital attenuator ICs in the stereo signal path. For a 2-channel audio design, this integration reduces BOM count, PCB area, and assembly complexity, while the 28-pin SOIC package keeps all audio and control signals on a single compact footprint.
Is LM4838MTE/NOPB compliant with RoHS and REACH environmental standards for consumer electronics manufacturing?
LM4838MTE/NOPB carries a lead-free Pbfree designation (JESD-609 e3) and is confirmed REACH Compliant, meeting both RoHS and REACH substance restrictions. This makes it directly usable in consumer audio products shipped to EU markets and other regions with strict environmental compliance requirements, without requiring process exemptions or material substitutions.
