It delivers 40mW per channel into a 32Ω load from a 3V to 3.6V supply rail, making it a direct fit for portable audio gear, set-top boxes, and line-out stages in consumer electronics that need a clean, low-noise headphone drive. The DirectPath™ architecture eliminates the need for large DC-blocking output capacitors, saving board space and reducing BOM cost. On-chip features include depop circuitry to suppress turn-on/turn-off clicks, differential inputs for noise rejection, a mute function, and short-circuit protection. Rated at 40mW per channel into 32Ω, this amplifier is sized for consumer headphone drivers. The 3V to 3.6V supply range matches common 3.3V system rails.","metaTitle":"TPA6138A2PW Class AB Stereo Headphone Amp, 40mW x 2 @ 32Ω","metaDescription":"TI TPA6138A2PW Class AB stereo headphone amplifier, 40mW per channel into 32Ω, 3V-3.6V supply, 14-TSSOP.
