The MAX9722AETE+T is a Class AB stereo headphone amplifier from Maxim Integrated's DirectDrive series. It delivers 130 mW per channel into a 32 Ω load from a 2.4 V to 5.5 V supply. The 16-TQFN (3x3 mm) package with exposed pad suits portable audio gear.
130 mW per channel — what it means for the headphone load
130 mW into 32 Ω drives most consumer headphones. The DirectDrive architecture eliminates DC-blocking output capacitors, saving board area and avoiding low-frequency roll-off.
Active lifecycle — no end-of-life pressure
The MAX9722AETE+T carries an Active product status. ROHS3 compliant. No last-time-buy notice or obsolescence risk for current production runs. For new designs, this part is safe to specify without a near-term requalification worry.
Sourcing and fit for the BOM line
The 16-TQFN (3x3 mm) footprint is shared by other DirectDrive amplifiers in the same package family, so a drop-in alternative exists if supply tightens — but the active status means no urgency to qualify a second source today.
