The Intersil ISL54000, ISL54001, ISL54002 family of devices are integrated audio power amplifier systems that combine stereo BTL 8Ω amplifiers in a single package. The devices are designed to operate from a single +2.7V to +5V power supply. All devices are offered in a 20 Ld 4x4 thin QFN package. Targeted applications include handheld equipment such as cell-phones, MP3 players, and games/toys. The ISL54000, ISL54001, ISL54002 parts contain two class AB bridge-tied (BTL) type power amplifiers for driving stereo 8Ω speakers. Each BTL is capable of delivering 800mW (typ) with 0.4% THD+N and 941mW (typ) with 1% THD+N of continuous average power into an 8Ω BTL speaker load when using a 5V supply. The ISL54001 and ISL54002 feature a 2:1 stereo input multiplexer front-end. This allows selection between two stereo sources. In addition the ISL54002 has the capability of mixing the stereo inputs.
