The Maxim Integrated MAX9725BETC is a Class AB stereo headphone amplifier in the DirectDrive® series, delivering 25mW per channel into a 16Ω load.
At 25mW into 16Ω, the MAX9725BETC drives most consumer earbuds and portable headphones to comfortable listening levels.
That means you can still design it into new products without worrying about a last-time-buy window closing.
It delivers 25mW per channel into a 16Ω load — enough for portable headphones and earbuds, but not for high-impedance studio headphones.
