Active audio codec in PQFP48
The LM4546AVHX: The PQFP48 footprint is a standard fine-pitch quad flat pack — the 0.5 mm pitch demands a clean solder-paste stencil and careful reflow profile, but the package is hand-reworkable with hot air if the board has good thermal relief on the ground paddle.
The LM4546AVHX is RoHS non-compliant, so it is not suitable for assemblies requiring RoHS exemption-free compliance; verify your BOM's exemption policy before committing.
