Description
The ISL54000 family of devices are integrated audio power amplifier systems that combine stereo BTL 8? 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 4×4 thin QFN package. Targeted applications include handheld equipment such as cell-phones, MP3 players, and games/toys. The ISL54000 parts contain two class AB bridge-tied (BTL) type power amplifiers for driving stereo 8? 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 8? BTL speaker load when using a 5V supply. All devices in this family feature low power shutdown, thermal overload protection and click/pop suppression. The click and pop circuitry eliminates audible transients during audio source changes and transitioning in and out of shutdown.
