The IntersilISL54003,ISL54005,ISL54006family of devices are integrated audio power amplifier systems that combine a mono BTL amplifier and stereo headphone amplifiers in a single device. The devices are designed to operate from a single +2.7V to +5V power supply. Targeted applications include handheld equipment such as cell-phones, MP3 players, and games/toys。
These parts contain one class AB BTL type power amplifier for driving an 8Ω mono speaker and two class AB headphone amplifiers for driving 16Ω or 32Ω headphone speakers。
The BTL when using a 5V supply 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。
Each headphone amplifier when using a 5V supply is capable of delivering 50mW (typ) with 0.3% THD+N and 94mW (typ) with 1% THD+N of continuous average power into a 32Ω headphone speaker。
When in Mono Mode these devices automatically mix the active left and right audio inputs and send the combined signal to the BTL driver. In Headphone Mode the active right channel input is sent to the right headphone speaker and the active left channel is sent to the left headphone speaker。
TheISL54005und ISL54006 verfügen über ein 2:1-Stereoeingangs-Multiplexer-Frontend. Dies ermöglicht die Auswahl zwischen zwei Stereoquellen. Darüber hinaus kann der ISL54006 die vier Eingänge des BTL-Treibers oder die beiden Eingangspaare der Kopfhörertreiber mischen。
These parts feature headphone sense circuitry that detects when a headphone jack has been inserted and automatically switches the active audio inputs from the mono BTL output driver to the headphone drivers. These parts also feature a logic control pin that can override the headphone sense input circuitry。
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.
