MAX9716 - (MAX9716 / MAX9717) 1.4W BTL Audio Power Amplifiers

General 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.

Key Features

  • a headphone sense input (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.
  • 1.4W into 4Ω at 1%.

19-3146; Rev 0; 1/04 Low-Cost, Mono, 1.4W BTL Audio Power Amplifiers General 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 www.DataSheet4U.com power. These devices also deliver 350mW continuous power into an 8Ω load while operating from a single +3.0V supply.
