124mW per channel into 16 ohms
The MAX9726AEBP+T is a Class AB stereo headphone amplifier from Analog Devices' DirectDrive series, delivering 124mW per channel into a 16 ohm load. That power level is enough to drive most consumer headphones to comfortable listening levels from a 2.7V to 5.5V supply rail, covering single-cell Li-ion or two-cell alkaline battery configurations. The DirectDrive architecture eliminates the need for large DC-blocking output capacitors, saving board space and reducing component count in portable audio designs. The amplifier operates over the full -40°C to +85°C industrial temperature range, making it suitable for battery-powered equipment that sees outdoor or automotive cabin environments.
Package and integration
Housed in a 20-ball WFBGA (UCSP) package measuring 2.03mm x 2.54mm, the MAX9726AEBP+T is a fine-pitch BGA that requires a controlled reflow profile and X-ray inspection for solder joint verification. The 0.50mm ball pitch means a 4-layer PCB with microvias is the practical minimum for fan-out, though a 2-layer board may work with careful routing on the outer rows.
Sourcing and availability
The MAX9726AEBP+T is an active Analog Devices part with no announced obsolescence. Sourced through authorized and independent distribution channels, it is quoted to order against your BOM quantity. Availability and current pricing are confirmed at the time of your RFQ.
