Rated for -40°C to +85°C ambient, so it handles the industrial temperature band — suitable for outdoor handhelds, dash-mount devices, or equipment stored in unheated warehouses. ## Package and footprint for layout Housed in a 12-WQFN with exposed pad (12-TQFN 4x4 mm), the thermal pad under the package sinks heat to the PCB copper — the layout should stitch vias under the pad to the ground plane to keep junction temperature within limits at full output. Surface-mount only — no through-hole variant. The 0.5 mm pitch QFN demands a solder stencil with appropriate aperture ratio for the exposed pad to avoid voids.","metaTitle":"MAX9725DETC Analog Devices DirectDrive Headphone Amp, 25mW","metaDescription":"MAX9725DETC Class AB stereo headphone amplifier, 25mW x 2 @ 16Ω, 0.9-1.8V supply, 12-TQFN.
