MAX9716 - Maxim Integrated Products

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

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 si.

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% THD+N ♦ 10nA Low-Power Shutdown Mode ♦ 73dB PSRR at 1kHz ♦ No Audible Clicks or Pops at Power-Up/Down ♦ Int.
