Housed in a 16-bump WLCSP measuring 1.92x1.94mm, it fits space-constrained portable designs where board area is the limiting factor. ## Supply range and output power trade-offs With a 2.5V minimum supply, the amplifier can run directly from a single lithium-ion cell near its end-of-discharge voltage; the 5.5V maximum allows use in 5V USB-powered systems without an external regulator. The 3.1W rating into 4Ω is the maximum output at the highest supply voltage — at lower supply rails the available power drops proportionally, so the actual loudspeaker SPL depends on the system's battery or rail voltage. Built-in depop circuitry suppresses the turn-on/turn-off pop that would otherwise couple into the speaker, and short-circuit and thermal protection prevent damage under fault conditions. The 16-bump WLCSP (1.92x1.94mm) is a wafer-level chip-scale package with no plastic overmold — the die backside is exposed, so the solder-joint reliability depends on the PCB pad design and the underfill if used in high-vibration environments. Surface-mount assembly requires standard reflow profiles for lead-free solder; the package is compatible with tape-and-reel handling (supplied on 7-inch reels per the TR suffix).","metaTitle":"SSM2529ACBZ-R7 Class D Amp, 3.1W Mono, 16-WLCSP","metaDescription":"Analog Devices SSM2529ACBZ-R7 Class D mono amplifier, 3.1W into 4Ω, 2.5-5.5V supply, -40 to 85°C, 16-WLCSP.
