Frequently Asked Questions
How does the 63 dB channel separation of LM4936MHX/NOPB benefit stereo headphone audio quality?
The LM4936MHX/NOPB achieves 63 dB of channel separation between its left and right outputs, meaning crosstalk is attenuated more than 63 dB below the primary signal level. This level of isolation preserves stereo imaging and spatial detail in headphone listening, preventing left-channel signals from audibly bleeding into the right channel across the 20 Hz to 20 kHz audio band.
What advantages does the integrated volume control in LM4936MHX/NOPB offer for portable audio design?
The integrated volume control circuit eliminates the need for an external digital potentiometer or analog attenuator, reducing the stereo headphone amplifier BOM by 2 to 4 components. This simplification shrinks PCB area and lowers system cost in battery-powered devices where every millimeter of board space and every milliwatt of quiescent current matters in a 2-channel audio path.
What HTSSOP package dimensions and lead pitch should PCB layout engineers use for LM4936MHX/NOPB placement?
The LM4936MHX/NOPB uses a 28-pin HTSSOP package with 0.25 mm lead pitch (TSSOP28,.25 equivalence code), requiring fine-pitch soldering capability. The plastic/epoxy body is JESD-609 e3 compliant, supporting lead-free reflow soldering. Layout engineers should follow Texas Instruments application notes for thermal pad design to manage Class AB amplifier dissipation at typical 3.3 V or 5 V supply voltages.
