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.
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%.
