That output level is typical for portable audio — enough to drive earbuds or low-impedance headphones to comfortable listening levels from a single-cell battery rail. The 0.9V to 1.8V supply range means this part runs directly off a Li-ion cell or a regulated 1.8V rail without a separate boost converter. The DirectDrive® charge-pump topology generates the negative supply internally, so you don't need DC-blocking capacitors on the output — a common failure point in conventional headphone amps. Housed in a 12-ball UCSP (2.02 x 1.54 mm), this is a wafer-level chip-scale package. The 0.5mm ball pitch requires a well-controlled SMT process — the solder mask opening and stencil thickness matter more here than for a larger QFN.","metaTitle":"MAX9721AEBC-T DirectDrive® Class AB Headphone Amp, 25mW","metaDescription":"MAX9721AEBC-T Analog Devices Class AB stereo headphone amplifier, 25mW x 1 @ 16Ω, 0.9-1.8V supply, -40°C to +85°C, 12-UCSP.
