Maxim MAX9718/MAX9719 Differential Input Audio Power Amplifier Datasheet
The MAX9718 and MAX9719 are differential‑input audio power amplifiers designed for portable devices with internal speakers. The MAX9718 is a single‑channel (mono) version, while the MAX9719 offers dual‑channel (stereo) operation. Both devices deliver up to 1.4 W per channel into a 4 Ω load with less than 1 % THD+N, operate from a single 2.7 V to 5.5 V supply, and include click‑and‑pop suppression and a low‑power shutdown mode.
The datasheet includes electrical characteristics, absolute maximum ratings, typical operating curves, pin descriptions, and package information for several UCSP, TDFN, μMAX, TQFN, and TSSOP options. It also outlines gain options (adjustable or fixed 0 dB, 3 dB, 6 dB), power‑supply rejection, common‑mode rejection, and thermal shutdown specifications.

What is the maximum output power of the MAX9718/MAX9719?
Each channel can deliver 1.4 W continuous average power into a 4 Ω load with less than 1 % THD+N.
What supply voltage range can the devices tolerate?
The absolute maximum supply voltage is –0.3 V to +6 V, while normal operation is from 2.7 V to 5.5 V single‑supply.
What is the maximum continuous output power per channel?
Each channel can deliver 1.4 W into a 4 Ω load while keeping total harmonic distortion plus noise below 1 %.
How low is the shutdown current of the amplifiers?
The shutdown input reduces quiescent current to less than 100 nA (typical 0.1 µA).
