Description

The MAX9716/MAX9717 audio power amplifiers are ideal for portable audio devices with internal speakers. A bridge-tied load (BTL) architecture minimizes external component count, while providing high-quality audio reproduction. Both devices deliver 1.4W continuous power into a 4Ω load with less than 1% Total Harmonic Distortion (THD) while operating from a single +5V supply. With an 8Ω load, both devices deliver 1W continuous power. These devices also deliver 350mW continuous power into an 8Ω load while operating from a single +3.0V supply. The devices are available as adjustable gain amplifiers (MAX9716/MAX9717A) or with internally fixed gains of 6dB, 9dB, and 12dB (MAX9717B/MAX9717C/MAX9717D), reducing component count.

A low-power shutdown mode disables the bias generator and amplifiers, reducing quiescent current consumption to less than 10nA. These devices feature Maxim's industry-leading, comprehensive click-and-pop suppression that reduces audible clicks and pops during startup and shutdown.

The MAX9717 features a headphone sense input (active-low BTL/SE) that senses when a headphone is connected to the device, disables the BTL slave driver, muting the speaker while driving the headphone as a single-ended load. The MAX9716 is pin compatible with the LM4890 and is available in 9-bump UCSP™, 8-pin TDFN (3mm x 3mm), and 8-pin µMAX® packages. The MAX9717 is available in 9-bump UCSP, 8-pin TDFN, and 8-pin µMAX packages. Both devices operate over the -40°C to +85°C extended temperature range.
