The mono output configuration with stereo headphone support means one channel drives both earpieces; the 0.9 V to 1.8 V supply range lets it run directly from a single-cell alkaline or Li-ion coin cell without a boost converter. ## Supply headroom and battery-powered fit Operating from 0.9 V to 1.8 V, this amplifier starts working when a battery has already dropped below 1.0 V, extending the usable runtime of a portable device. The -40°C to +85°C temperature grade covers consumer and industrial ambient ranges. The 12-UCSP package (2.02 x 1.54 mm) is a wafer-level chip-scale package — the footprint matches the die size, so the PCB land pattern must follow the application note exactly for solder-joint reliability under thermal cycling.","metaTitle":"MAX9721BEBC-T Analog Devices DirectDrive Headphone Amp, 25mW","metaDescription":"MAX9721BEBC-T Class AB stereo headphone amplifier from Analog Devices, 25mW x 1 @ 16Ohm, 0.9V-1.8V supply, 12-UCSP.
