The IntersilISL54004device is an integrated audio power amplifier system that combines a mono BTL amplifier and stereo headphone amplifiers in a single device. It can operate from a single +2.7V to +5V power supply and is offered in a 20 Ld 4x4 TQFN package. Targeted applications include handheld equipment such as cell-phones, MP3 players, and games/toys。

TheISL54004part contains 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 the part automatically mixes the left and right audio inputs and sends 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。

TheISL54004has a four-level programmable gain stage to boost the audio signal. The part requires no external gain setting resistors。

TheISL54004part features headphone sense input circuitry that detects when a headphone jack has been inserted and automatically switches the audio inputs from the mono BTL output driver to the headphone drivers. The part also has a logic control pin that can override the headphone sense input circuitry。

The part also features low power shutdown, thermal overload protection and click and pop suppression. The click and pop circuitry prevents click and pops at the speakers when transitioning in and out of shutdown。
